EVENT

Stargazing party

American humorist Fred Allen once said, “A celebrity is a person who works hard all his life to become well known, then wears dark glasses to avoid being recognized.” Not so this weekend at the Hollywood Collectors & Celebrities Show in North Hollywood, where more than 75 stars of stage, screen and television will be on hand to sign autographs (for a fee, of course). Scheduled attendees include Janet Leigh, Hayley Mills, Dennis Weaver, Alan Young, Mackenzie Phillips and Samantha Eggar. Plus there will be dealers selling all kinds of Hollywood memorabilia and other collectibles.

Hollywood Collectors & Celebrities Show, Beverly Garland’s Holiday Inn, 4222 Vineland Ave., North Hollywood. Saturday, 10 a.m.-5 p.m.; Sunday, 10 a.m.-4 p.m. $10 admission per day, additional charges for autographs. (352) 683-5110.

THEATER

Scooby-Doo for all ages

Scooby Doo -- he’s not just for kids any more. You can bet it won’t just be tykes in the audience for “Scooby-Doo in Stagefright -- Live on Stage!” at the Kodak Theatre. The animated canine and his man-servant, Shaggy, are official pop culture phenoms. British comedian Eddie Izzard calls Shaggy and Scooby “fantastic because they are cowards ... they believe in cowardice and sandwiches,” even suggesting that the only character in all of English literature on a par with the duo may be Falstaff, “a Shakespearean character -- it’s that level of greatness!” Well, at least we know it won’t end with anybody being stabbed, poisoned or otherwise dying in her lover’s arms.

“Scooby-Doo in Stagefright -- Live on Stage!” Kodak Theatre, 6801 Hollywood Blvd., Hollywood. Today and Friday, 7 p.m.; Saturday-Sunday, 11 a.m. and 2 p.m.; ends Sunday. $19-$40. (323) 308-6363.

MUSIC

Doubling up the Passion

The largest of Bach’s works, the “St. Matthew Passion,” emerged fully formed in 1727 and was never significantly revised over the years. How different was his “St. John Passion,” which came earlier (1724) and underwent revisions with every subsequent performance. Even toward the end of his creative life, Bach was still tinkering with it. The two Passions, acknowledged as monuments in Western music, are rarely performed back to back, but that’s exactly what Masaaki Suzuki and his highly acclaimed Bach Collegium Japan offer this weekend at UCLA.

Bach Collegium Japan, Royce Hall, UCLA, 10745 Dickson Plaza, Westwood. “St. John Passion,” Friday, 8 p.m. “St. Matthew Passion,” Saturday, 8 p.m. $15 to $50, each performance. (310) 825-2101.

THEATER

Stritch on Stritch

In her Tony Award-winning autobiographical show, “Elaine Stritch at Liberty,” the stage luminary takes audiences on a tuneful odyssey through her eventful life and long career, filled with such signature songs as Stephen Sondheim’s “The Ladies Who Lunch” and “I’m Still Here,” along with anecdotes about notables ranging from Marlon Brando to Noel Coward and about her personal highs and lows. The production is directed by George C. Wolfe.

“Elaine Stritch at Liberty,” Ahmanson Theatre, 135 N. Grand Ave., L.A. Opens Wednesday. Runs Tuesdays-Saturdays, 8 p.m.; Sundays, 5 p.m.; ends April 27. $25 to $68. (213) 628-2772.

DANCE

A Perm reprise

When the Perm State Ballet (Russia’s third-largest company) danced locally for the first time three years ago, The Times noted the “obvious budget limitations” of the tour repertory. “But they work their hearts out,” the review concluded, and “the style is elegant and unified.” In 2002, the company upgraded its image with fine productions of two full-length ballets set to music by Prokofiev. Now it’s Tchaikovsky’s turn: “Swan Lake” and “The Sleeping Beauty” in two performances each in traditional Soviet-style stagings (“Swan Lake” with a happy ending, for instance). As before, the company’s 50-member orchestra will provide accompaniment and, once again, casting is a deep, dark secret.

Perm State Ballet, Cerritos Center for the Performing Arts, 12700 Center Court Drive, Cerritos. “Swan Lake,” Friday, 8 p.m., Sunday 2 p.m.; “Sleeping Beauty,” Saturday, 2 and 8 p.m. $37 to $47. (800) 300-4345.

POP MUSIC

Heart of darkness

If ever there was a band whose name captured its sound, it’s Black Heart Procession. The San Diego duo and its supporting musicians march to the dirge-like pace of a grand gothic vision, shrouding their followers in a veil of deep, dark and mysterious atmosphere. Their El Rey show should feature music from the group’s latest album, the murder-mystery-themed “Amore del Tropico.”

Black Heart Procession, El Rey Theatre, 5515 Wilshire Blvd., L.A., Friday, 8 p.m. $14. (323) 936-4790.

ART WALK

Creative hobnobbing

You, too, can visit with creative artists in their studios, then hobnob with them while sipping white wine, mouthing truisms and consuming canapes. The Sawdust Art Festival Art Walk Studio Tour offers a rare opportunity to visit the private studios of more than 60 Laguna Beach artists who work with paint, sculpture, jewelry, glass and other media. After the tour, patrons are invited to a reception with drinks, hors d’oeuvres and entertainment.

Sawdust Art Festival Art Walk Studio Tour, 935 Laguna Canyon Road, Laguna Beach. Saturday, 10 a.m.-4 p.m.; Sunday, 10 a.m.-3 p.m. $40 to $55. (949) 494-3030.

JAZZ

Have mallet, will travel

Vibraphonist Stefon Harris is barely 30 and already he’s being favorably compared to such jazz greats as Lionel Hampton, Gary Burton and Milt Jackson. Harris scored big time in 1998 with his debut CD, “A Cloud of Red Dust,” and followed that with two Grammy-nominated efforts: “Black Action Figure (1999) and “Kindred” (2001), in which he led a quartet with pianist Jacky Terrasson. A CD of Harris’ acclaimed 11-movement jazz suite, “The Grand Unification Theory,” was released in February, and now he’s taking a 12-piece ensemble on the road, performing the 70-minute musical sojourn that’s spiced with Latin, African and classical influences. This week the piece makes its West Coast premiere at the Jazz Bakery. The tour ensemble features Harris on vibes, Isaac Smith on trombone, Kim Thompson on drums, Jeremy Pelt on trumpet, Jeff Nelson on trombone, Jeff Weisman on flute, Sean Conly on bass, Tim Warfield on tenor sax, Mark Vinci on clarinet, Myles Weinstein on timpani, Xavier Davis on piano and Kahlil Bell on African percussion.

Stefon Harris, the Jazz Bakery, 3233 Helms Ave., Culver City. Thursday-Sunday, 8 and 9:30 p.m. $30 to $35. (310) 271-9039.

MOVIES

Next up: ‘The Son’

Olivier Gourmet won the best actor prize at Cannes last year for his performance in Jean-Pierre and Luc Dardenne’s “The Son.” Gourmet plays a divorced shop teacher at a vocational training center whose solitary existence is shaken by the arrival of a new student. The Dardenne brothers are best known for their 1999 Cannes Golden Palm winner, “Rosetta,” which also co-starred Gourmet.

“The Son,” unrated, opens Friday exclusively at the Laemmle Music Hall, 9036 Wilshire Blvd., Beverly Hills, (310) 274-6869.
