This was brought to my attention, as usual, by the fine posters over at WCMB. Norko and I saw both of these gentlemen at the NWA Legends Fanfest in Atlanta a few years ago. Austin Idol is also one of GW's (my dad) favorite wrestlers of all-time.
Two old rivals squaring off isn't particularly interesting in and of itself. They are teasing a special guest referee. The fact that Lawler is stepping into the ring again after his heart attack makes this more noteworthy to me. I'm not sure how active "The King" has been other than a tag match with Dory Funk, Jr.
Good luck to Memphis Power Wrestling who is promoting this show and is also promising more legends to be announced.
