They're wrackin' their brain
To think of a name
To give to this tune
So Frankie can croon
And maybe old Bing
Will give it a fling
And that will 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 rockin' rhythm through in the day

So they call it Opus One
Come on lads, on and jump
Hey, hey, hey!
It's Opus One
This ain't no time to slump, maybe!

If Benny the King
Would do it in swing
And old Mister G
Could rock it for me
There's never a doubt
You'll knock yourself out
If ever you should hear Opus One
