Just watched the recording from last night. Thoroughly enjoyed it, along with, oh, 100,000 others in the audience!
C'mon, how many of the dislikes are real? Wouldn't you like to be doing that at 70? If not, why are you playing at all?
If they were truly no good at all, you wouldn't have just watched them - because they would never have made it there!
Good on 'em!
