I know Marty Stuart probably regrets doing so, but George Jones showed up at his TV show once not long before he passed (probably unannounced) and Marty didn't let him sing. Now they had plenty of room for Leroy Troy, Krom only knows it would have been a shame to bump Leroy and let George have a go at it, but I'm thinking Marty didn't want to embarrass, George, the band, and the tiny little audience. Towards the end of his career George mad some really bad appearances on TV. I say all of this being a dyed in the wool George Jones fan. There is just a time to hang it up.
