Looks like sometimes listeners have a better memory than artists... ;0)

In the long run avoiding these repetitions is in the owen interests of the artists, otherwise people would say "oh no, I won`t go to see him again, he`ll do the same stuff again once more..."

That said I will tolerate the repetition of certain jokes if the music is worth it and the repetition of songs if I like them - - but both will get boring after a while (and boring is not entertaining).
