EJ,

I am not opposed to including Elvis. Hendrix, Chuck Berry, and other rock n roll types at all--in fact, if I was going to list anyone, they would have been on my list--

Bonnie,

A TK is half yiddish name for is a person who does what might be called, "buttering up"--

Don Meixner,

Nice list and explanations--I was particularly glad to see the dancers listed, because the connection between American music and tap dance is usually overlooked--
