"Mony Mony" is a song by American pop rock band Tommy James and the Shondells, released in 1968 as the second single from the album of the same name. It reached No. 1 on the UK Singles Chart and No. 3 in the U.S. Written by Bobby Bloom, Ritchie Cordell, Bo Gentry, and Tommy James, the song has appeared in various film and television works such as the Oliver Stone drama Heaven & Earth. It was also covered by English rock musician Billy Idol in 1981, and again in a live 1985 recording. His second version, not released until 1987, became a bigger hit than the Shondells' 1968 original, reaching No. 1 on the Billboard Hot 100 and top 40 internationally, and revived public interest in the Shondells' original. Idol's 1981 version failed to chart, although it did reach number seven on the dance charts.
