Looking for Orchestra Hall 1982 tape

Does anyone but me have the 12/26/1982 Orchestra Hall concert broadcast on Cities 97? Even Michael didn't have a copy. I called my brother from the Hall and asked him to tape it but he did a bad job. Brothers, huh? It's the concert where Michael played two songs on the piano after intermission. Not to be confused with the 1984 concert which was also broadcast.

Thanks,
Cindy
