"Sing A Happy Song" by The O'Jays

Formerly known as The Triumphs, The O'Jays dominated the charts in the 70s with classic hits like "Back Stabbers" (#3), "Love Train" (#1), "For The Love Of Money" (#9), "I Love Music (Part 1)" (#5), and "Use Ta Be My Girl" (#4). The R&B group from Ohio ranks as the 42nd most successful chart artist of the 70s.

Things started to fizzle for the group in the 80s, but they continued to record well into the 90s. Their last chart appearance was in 1997 when "Baby You Know" reached #76. This means they had chart hits across four decades, not an easy feat for any artist (The O'Jays first chart appearance goes all the way back to 1963 when "Lonely Drifter" climbed to #93).

"Sing A Happy Song" was the lead single from their 1979 effort, "Identify Yourself." Surprisingly, this perky feel-good tune bubbled under. The next single from the album, "Forever Mine," did better, reaching #28.
