WOW PETER....NOW THAT IS A GOOD QUESTION!!!
I think this is probably, as you pointed out, almost IMPOSSIBLE to answer definitively!! Although new information about Elvis' concerts seems to come out all the time, since we simply don't have a setlist for every single show Elvis ever gave, this would be a difficult question to answer conclusively!
Plus....with all the one liner's he sang...oh my gosh....this could take forever!!! :bash:
Anyone want to venture a guess on this one????? (BOBBY....where are you???)
