I'm wrackin' my brain to think of a name To give to this tune so Perry can croon And maybe ol' Bing will give it a fling And that'll start everyone hummin' the thing The melody's dumb repeat and repeat But if you can swing, it's got a good beat And that's the main thing, to make with the feet 'Cause ev'ryone's swingin' today Bridge So I call it Opus One It's not for Sammy Kaye, hey, hey, hey Opus One it's got to swing not sway, maybe If Mister Les Brown could make it renowned And Ray Anthony could swing it for me There's never a doubt you'll knock yourself out Whenever you can hear Opus One
