Polished concludes this week with Sarah Rayne of the excellent Los Angeles band Babes. (See them in San Francisco on December 11 and their hometown on December 12.) Even if you don’t know Babes, you know Rayne’s voice: She was Sid’s little sister in the original Toy Story. She did a bunch of other acting as a kid/adolescent as well, but has stuck to music lately. Before Babes went out for its first big U.S. tour, Jamie Lee talked to Rayne about her interesting life.
