GOINGS ON SANTA BARBARA : Drawing on Fame : Celebrity doodlings will be auctioned off to raise funds for renovating Santa Barbara’s Lobero Theatre.

Have you ever been curious about what Bo Derek might doodle while she’s talking on the phone or sipping her coffee?

Ponder no more. It’s a heart. Also keeping in character, George Burns draws glasses with a cigar. And Alan Alda, like most people, makes those lines and boxes and other haphazard shapes.

These celebrities, plus Vincent Price, Carol Burnett, Elizabeth Taylor, Burt Reynolds, Brooke Shields, James Stewart, Jane Seymour and many others have donated their doodlings to the Lobero Theatre Foundation.

The works will be auctioned off March 28 to raise money for theater renovations. State law requires that by September, 1995, the Lobero be strengthened to meet seismic standards, or close its doors.

In addition to the doodlings and some photographs, there will be selected items from the estate of Dame Judith Anderson as well as costumes from theater productions. A cocktail buffet and auction preview begin at 5:30 p.m. at the Lobero, 33 E. Canon Perdido St. The auction starts at 7:30 p.m. Tickets are $50. Call 966-4946.
