Three Dog Night is an American rock band formed in 1967, founded by vocalists Chuck Negron, Cory Wells, and Danny Hutton. This lineup was soon augmented by Jimmy Greenspoon (keyboards), Joe Schermie (bass), Michael Allsup (guitar), and Floyd Sneed (drums). The band had 21 Billboard Top 40 hits between 1969 and 1975, with three hitting number one. Three Dog Night recorded many songs written by outside songwriters, and they helped to introduce mainstream audiences to writers such as Randy Newman, Paul Williams, and Hoyt Axton.
