In January and February 1992 Gunderson returned to San Diego to portray Peter in Wendy Wasserstein's The Heidi Chronicles at the Hahn Cosmopolitan Theatre. Later that year, he co-created and starred in another original cabaret revue, Back to Bacharach and David, which featured music by Burt Bacharach and Hal David, arranged by Gunderson. The revue's script was written by Gunderson and Kathy Najimy, who directed the revue. He and Najimy also appeared together in the film Topsy and Bunker: The Cat Killers (1992).
