D D6 D D6 I'm wrackin' my brain to think of a name Dm+7 Dm6 Dm+7 Dm6 To give to this tune so Perry can croon; Em7/9 A7 Em7 A7 And maybe ol' Bing will give it a fling, D Fdim Em7 A7 And that'll start everyone hummin' the thing. D D6 D D6 The melody's dumb repeat and repeat Dm+7 Dm6 Dm+7 Dm6 But if you can swing, it's got a good beat, Em7/9 A7 Em7 A7 And that's the main thing, to make with the feet, D G D 'Cause ev'ryone's swingin' today. Bridge: F Gm So I call it Opus One Bb C7 F Dm Bb C7 It's not for Sammy Kaye, hey, hey, hey. G D7 G Gdim Opus One...it's got to swing not sway, maybe. D D6 D D6 If Mister Les Brown could make it renowned, Dm+7 Dm6 Dm+7 Dm6 And Ray Anthony could swing it for me, Em7/9 A7 Em7 A7 There's never a doubt you'll knock yourself out Em7 A7 D6 Whenever you can hear Opus One.
