The following year saw the release of their second album entitled How Much, How Much I Love You, (title track covered side one, "Beauty and the Beast" completed side two) utilizing the same basic formula. Both songs became top five disco hits. This was followed closely by the group's biggest hit, "Thank God It's Friday", the theme song from the film of the same name. It peaked at #23 R&B, #22 on the Billboard Hot 100 chart and #1 for six weeks on the Hot Dance Music/Club Play chart. The soundtrack, which featured Donna Summer's "Last Dance" and the Commodores "Too Hot Ta Trot", was nominated for several Grammy Awards.
Their third and final album, You Must Be Love was released in 1979, but met with less success. Shortly thereafter the group disassembled.
