The locker nameplate states Klasson. Probably Eric Klasson 1982 Wrestling.. So must be Crisler sign from 1982 era.

I recently took this photo at an Andy Summers of The Police concert. The b&w backdrop image was taken by him with Stewart Copeland resting on his hands. Must have when The Police played Crisler Arena April 7, 1982.

Tunnel too small. Obviously lights an issue in the past but getting a big stage into the stadium is the only issue. Period.
