This song is so heavenly. The love maestro himself, Barry White, fronted the Love Unlimited Orchestra, and definitely gave this song his own flair, classical with a tinge of disco. In the 70s, many groups had lush instrumentation: Chicago, ELO, Earth, Wind and Fire. This song, however, was one of the few purely orchestral arrangements to make it to number one on Billboard’s Hot 100 and deservedly so.
