Very nice of you to mention that - I find Elvis to be a lot more giant-like than the Beatles though.
It would have been rather interesting if the recordings made at the jam sessions were still there..
Funny remarks were:
Beatles: Elvis, where are the birds, man?
Elvis: Well, I guess they're out in the yard or something...
Beatles: No man, I mean the girls! Where are the girls?
Funny that in the US it is not common to think of women as 'birds'. I'd rather just say 'women'!
