Last month my ten year old son developed a sudden interest in scat singing courtesy of Scatman John. I wasn't going to let him hold his claim that Scatman John was the greatest EVER. I trotted out Cab Calloway and Ella Fitzgerald. Minnie The Moocher scored well, but it was this clip of Ella in her later years that did it for me. As I approach 50, those that know how to hold their cool get extra points.
Got to hand it to Scatman though. He prompted a nice bit of the evening. Scat singing didn't enter my consciousness until college I think.
