You're right Nick .... Elvis was and still is cool. Have you ever met someone that didn't like his music ?
I'll tell you how cool he is..... my parents (now in their 60's and 70's) still love him, my wife and I (40's) love him, my 23 year old son thinks he's awesome, and my two younger kids (6 and 11) love him. He transcends time and generations. Amazing.
He was one of the original cool Dudes....... cool enough to be SLY.
