I'm w[D]rackin' my [D6]brain to [D]think of a n[D6]ame
To [Dm+7]give to this [Dm6]tune so [Dm+7]Perry can [Dm6]croon;
And [Em7/9]maybe ol' [A7]Bing will [Em7]give it a f[A7]ling,
And [D]that'll start [Fdim]everyone [Em7]hummin' the [A7]thing.
The [D]melody's d[D6]umbrep[D]eat and re[D6]peat
But [Dm+7]if you can [Dm6]swing, it's[Dm+7] got a good [Dm6]beat,
And [Em7/9]that's the main [A7]thing, to [Em7]make with the [A7]feet,
'Cause [D]ev'ryone's s[G]wingin' to[D]day.
Bridge:
So I call it[F] Opus O[Gm]ne
It's [Bb]not for S[C7]ammy K[F]aye, [Dm]hey, [Bb]hey, [C7]hey.
O[G]pus One...it's g[D7]ot to swing not [G]sway, [Gdim]maybe.
If [D]Mister Les B[D6]rown could [D]make it re[D6]nowned,
And [Dm+7]Ray Antho[Dm6]ny could s[Dm+7]wing it for [Dm6]me,
There's [Em7/9]never a [A7]doubt you'll [Em7]knock yourself [A7]out
When[Em7]ever you can [A7]hear Opus [D6]One.
