Three Dog Night is an American rock band, best known for their music recorded between 1968 and 1975. They formed in 1968 with a line-up consisting of Danny Hutton, Cory Wells and Chuck Negron. The three lead singers were backed by Jimmy Greenspoon (organ), Joe Schermie (bass), Mike Allsup (guitar) and Floyd Sneed (drums). The band registered 21 Billboard Top 40 hits (with three hitting number one) between 1969 and 1975. Their version of "It's for You" typified the band, but it was their original arrangement of lesser-known songwriters' work that brought them mainstream exposure. As of 2013, they are still recording and making live appearances.
