SMALL FACES

Billy Corgan’s still feuding with former Smashing Pumpkins manager Sharon Osbourne (their mutual lawsuits are still pending). But the singer will appear on an album due from the new label owned by Osbourne and hubby Ozzy and distributed through Priority Records. Corgan is one of the vocalists on “Iommi,” a solo album by Ozzy’s Black Sabbath bandmate, guitarist Tony Iommi. Due Oct. 10, the album also features vocals by Foo Fighters’ Dave Grohl, the Cult’s Ian Astbury, Henry Rollins, Billy Idol, Skin of Skunk Anansie, Phil Anselmo of Pantera, Serge Tankian of System of a Down and Peter Steele from Type O Negative. . . .

Peter Case, who started out as a street busker playing for coins tossed into his guitar case, is returning to that format for charity Saturday with performances at three Los Angeles-area Borders stores. Benefiting the homeless aid organizations MEND (Meet Each Need with Dignity) and Women’s Care Cottage, Case will play for donations first at the Santa Monica location starting at noon, then move to Sherman Oaks at 4 p.m. and Pasadena at 8 p.m.
