Written by Even Stevens, who followed producer Ron Haffkine into the studio bathroom to pitch him the song. "When You're in Love with a Beautiful Woman" first appeared on the band's 1978 album Pleasure and Pain. Riding the disco wave in 1979 it belatedly became an international hit, reaching number six on the Billboard Hot 100 singles chart in the USA and doing even better in the UK where it spent three weeks at number one in the UK Singles Chart in November 1979. The song was subsequently added to the band's 1979 album Sometimes You Win. It features background vocals by three female singers.
