As an addendum to yesterday's blog, I'm adding this clip of Cab Calloway, on Sesame Street of all things, demonstrating the Jazz Scat that he helped make so famous.

Jason Mraz does this, and even drew the audience into the Scat Echoing like Mr. Calloway does here. You know it, Mom. You just didn't have the benefits of the Sesame Street and You Tube generations.
