Parker Richard Campbell Mike Cuneo </Td> </Tr> <P> Three Dog Night is an American rock band . They formed in 1967 with a line - up consisting of vocalists Danny Hutton, Cory Wells, and Chuck Negron . This lineup was soon augmented by Jimmy Greenspoon (keyboards), Joe Schermie (bass), Michael Allsup (guitar), and Floyd Sneed (drums). The band registered 21 Billboard Top 40 hits (with three hitting number one) between 1969 and 1975 . It helped introduce mainstream audiences to the work of many songwriters, including Paul Williams ("An Old Fashioned Love Song"), Hoyt Axton ("Joy to the World"), Laura Nyro ("Eli's Comin"'), Harry Nilsson ("One"), Randy Newman ("Mama Told Me Not to Come"), and Leo Sayer ("The Show Must Go On"). </P> <P> The official commentary included in the CD set Celebrate: The Three Dog Night Story, 1964--1975 states that vocalist Danny Hutton's girlfriend, actress June Fairchild (best known as the "Ajax Lady" from the Cheech and Chong movie Up In Smoke) suggested the name after reading a magazine article about indigenous Australians, in which it was explained that on cold nights they would customarily sleep in a hole in the ground while embracing a dingo (wild dog). On colder nights they would sleep with two dogs and, if the night was freezing, it was a "three dog night". </P>
