Let's see....
In the 70's
Elvis
The Doobie Brothers (2 times)
Chicago (2 times)
Boston (when they only had one album)
The Beach Boys (including all original members)
Linda Ronstadt (when she was a skinny knock-out)
Kansas
The 80's
Pat Benetar (at Brothers Music Hall in Birmingham - before they had a hit record)
Jimmy Buffett (have seen Buffett 20+ times, beginning in the late 70's through 2001, the most times in one year was 3 in 1980)
The Little River Band
Hotel (Nobody outside of B'ham knows this band, but they were a favorite at the time)
Cheap Trick (this might have been in 1978 or 1979)
The 90's
Elton John/Billy Joel (joint tour - rode the elevator with BJ)
The Rolling Stones (one of their many farewell tours)
As you can see I don't go to many. AND I'm old. (not as old as Oldguy - I think his concert list includes Mitch Miller and Tommy Dorsey).

Now I just go see Buffett once a year and that's about it. Concerts are too expensive. I paid $15 to see Elvis in 1976. At that time most concerts were around $6. I stopped going to concerts in the 80's when ALL the prices were above $15, because I said I wouldn't pay more to see some New Wave band than I did to see The King of Rock and Roll. :lol: :roll: It also chaps my butt that you have to go through Ticketmaster to get a ticket. What a racket! :x
