I think this could be cheating but very clever.I'll redo it with three shows.
1993 the Rolling Stones Voodoo Lounge.
The Who back in ' 89.
A tie. 1988 Elton John, Reg Strikes Back Tour.
The Kinks. ' 88 , very small venue.
Crosby Stills Nash & Young, '85 - 8 ish,.
1984 Aerosmith. Before they wrote novelty songs.
The Beach Boys. I saw them seven or eight times. They kept coming back to my local Neighborhood Theatre.
Tina Turner 1984. The Private Dancer tour.
I can't pick a tie breaker.
