Cab Calloway
The Scat Song (1933)
[Scat]

[Spoken]
[Bennie Payne?] Say, what you doin', boy?
[Cab] Oh, man, I'm just scatting and going right on to town, Satchmo!

When your sweetie tells you, everything'll be okay, just

If you feel like shoutin', advertise it just this way, and skoo-doo

Don't you give a hang what words you use at any time
Sing this silly language without any reason or rhyme
When you face the preacher, there's only one thing to say

[Scat]
