Editors: On Aug. 26, from 7:30 p.m. to 9 p.m., Levitt will be at the Troubadour Bookstore, on Pearl Street, Boulder, reading excerpts from his book on Joe Frisco, signing copies and talking about vaudeville. Joe Frisco, a vaudeville comic and jazz dancer, was probably as famous in the 1920s and ‘30s as television comedian Jerry Seinfeld is in the ‘90s. But soon after he died in 1958, Frisco slipped into obscurity.
