I think the most fun concert was at the Wisconsin state fair years ago when the entire crowd was singing with Kenny Rogers. Perhaps the classiest acts were Frank Sinatra, and even earlier the 5th Dimension. I saw Elvis the year before he died but we were in the last row of the "nose bleed section" and had to use binoculars. Oh, the other great show was Ray Stevens when he was in Branson, and Yakov Smirnov was good too.
