My first concert was late 60s when in high school - Paul Revere and the Raiders at the Masonic Temple in Davenport, Iowa! So exciting! Best ever was Elton John in 1972 at Iowa State Univ.
Gotta ask those of a similar age - ever go to a Rod McKuen concert? I think it was at a Holiday Inn in Des Moines, probably around 1970ish. How about Anne Murray, also at the Iowa State fair. :-)
