Cant recall exact date but it was a house show at the Philly Spectrum in 88.Powers of Pain were on the card IIRC so had to be that Summer.
Crazy looking back both Spectrum and Civic Center,2 meccas of wrestling back then are long gone now.
Here are two of the shows in the summer at the Spectrum, either of these seem familiar?
