I didnt realize until recently that Elvis was playing 3 -4 gig per night during his monthly Vegas visits,
I gig a Bit.. 3 wold be draining ..especally if it was every night , nearly impossible to keep up.I didn't hear four, but he did an afternoon show, a dinner show and a midnight show. It was all far too much for him. No star would do anything like that today - and quite right too. Then the stadium shows were draining too.
