Steam was a pop music group best known for their 1969 #1 hit song "Na Na Hey Hey Kiss Him Goodbye".

A so-called one-hit wonder, the band -- originally a studio group -- had already broken up by the time the song (intended to be a throwaway B-side, hit) was released. The song became a surprise smash hit and rose to the top of the pop charts instantly. A touring band was quickly assembled by the producers, but did not last very long. The group and song were largely forgotten in the ensuing days of Disco until the 1977 Major League Baseball season, when Chicago White Sox organist Nancy Faust began playing the tune when opposing pitchers were relieved, or when the Sox had clearly won the game. Fans began singing along, and playing the song during sporting events gradually became a tradition. Today the Steam hit is commonly heard at arenas and stadiums throughout the US and around the world.

In addition, the song was revived for the 2000 movie Remember the Titans, and in 2004 in the film "Raising Helen".
