Singer Mel Torme called this tune "the national anthem for group singers." It's been recorded by everyone from Frank Sinatra to George Shearing, and most recently by Michael Buble on his CD, Call Me Irresponsible. This is the quintessential vocal group number! The voice parts are easy, so it's a great piece to work on tone and blend for any ensemble of any size, including beginning vocal jazz groups. Highly recommended!
