At the 3:21 mark of this video from the Inside The Ropes channel, Jerry Lawler discusses his anger toward Paul Heyman. It stems from their animosity going back to Memphis in the late 1980's.
Jerry believes that what Paul saw in Memphis then was applied to ECW's hardcore style without crediting Memphis. He talks about the heat that Jerry received during his surprise appearance at Wrestlepalooza 1997 at the ECW Arena in Philadelphia.
Lawler goes into more stories about his being on set for the "Man On The Moon" movie filming.
