Three Dog Night recorded Harry Nilsson's "One" for their eponymous debut album in 1968. The single of "One" released in 1969 reached number five on the Billboard Hot 100 chart.

 

The point is we're really picky about things. We could have been like a lot of groups and crammed things down the public's throat because we wrote them. And, of course, you make a lot of money writing your own songs. But I don't think anybody has really felt really confident that we've written anything of the caliber of Nilsson or Randy Newman. And it's proved out to be correct.
