We all know that longest set of Elvis concert was on Closing Show 1976 in Lake Tahoe (it was cca 110 - 120 minute show!!!

:
But what was next long show? I heard that Pittsburg show 76 was very long for Elvis. How long are "long" Elvis concerts?
P.S.: I know that Elvis standard concert set was around 60min long, but why? I think that it?s really SHORT running time! When I was on Stones or on Deep Purple last year, both bands played for longer time (DP - 110min; Stones - 130 min!

, and concerts seems short! DP played 16 songs; Stones 19 songs, and after show I thought - it was great (DP concert was best show I ever seen!!!

, but it could be longer! Because I know, that running time of Elvis shows was "short" I think that it had to be disappointing for lot of fans to see their superstar for only one hour! What do you think about my point of view?
I love Elvis shows, but lenght of his shows is one of largest minus of his concerts for me!
