By the end of the 1960s, Sonny and Cher's music had ceased to chart. According to Berman, "the heavy, loud sound of groups like Jefferson Airplane and Cream made the folk-rock music of Sonny and Cher seem too bland." Cher later said, "I loved the new sound of Led Zeppelin, Eric Clapton, the electric-guitar oriented bands. Left to myself, I would have changed with the times because the music really turned me on. But didn't like it—and that was that." Their monogamous lifestyle during the period of the sexual revolution and the anti-drug position they adopted at the height of the drug culture lost them popularity among American youths. According to Bego, "in spite of their revolutionary unisex clothes, Sonny and Cher were quite 'square' when it came to sex and drugs." In an attempt to recapture their young audience, the duo produced and starred in the film "Good Times" (1967), which was commercially unsuccessful.
