Throughout his career Forrest worked exclusively with the composer-lyricist Robert Wright. The pair had an affinity for adapting classical music themes and adding lyrics to these themes for Hollywood and the Broadway musical stage. Wright said that the music was usually a 50-50 "collaboration" between Wright & Forrest and the composer. While both men were credited equally as composer-lyricists, it was Mr. Forrest who worked with the music. 'Kismet' was one of several works Forrest created with Wright that was commissioned by impresarioEdwin Lester for the Los Angeles Civic Light Opera. Song of Norway, Gypsy Lady, Magdalena, and their adaptation of The Great Waltz were also commissioned by Lester for the LACLO. The LACLO then exported most of these productions to Broadway. Forrest and Wright won a Tony Award for their work on Kismet and in 1995 they were awarded the ASCAP Foundation Richard Rodgers Award. He was cremated at Van Orsdel Crematory, Miami.
