I’m rackin’ my brain to think of a name to give to this tune
So Perry can croon and maybe old Bing will give it a fling
And that’ll start everyone hummin’ a 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 it complete
‘Cause everyone’s swingin’ today

So they call it Opus One, but not for Sammy Kaye
Hey, hey, hey, Opus One, it’s got to swing that sway, baby
And Mr. Les Brown Can make it renown
And Ray Anthony He can rock it for me
There’s never a doubt you’ll knock yourself out
Whenever you can hear Opus One
Whenever you can hear Opus One
Whenever you can hear Opus One
