EC on his comeback tour in 1974/75 made a trip thru Memphis.
I think EC and his band went to a movie at a rented out theater there in Memphis with the King and his entourage. Elvis apparently from what I remember had little to say that evening.
The Stones pulled Scotty on stage in front of 90.000 in Hamburg in 1998. Very sad that he didn´t play a note. And very sad that even after the introduction 89.000 didn´t know who he was.
This is from "A Tribute To The King" by Scotty Moore and friends(Universal ) all shot at Abbey Road Studios Co-executive producer: Bill Wyman Music Producers: Ron Lively/Scotty Moore/Bill Wyman. The basic band is Bill's. One of the best performances on this(IMO) is David Gilmour's version of "DON'T".
