Yeah I guess we played kinda long.and the show was exausting so You really can't blame BJ for not playing so long every night.
and as for the vocals yeah they are that dificult so anybody who says that Jon has lost his voice I suggest you should try to sing a full BJ set list because I can testify that it is not easy.
all I gotta say is thank god I knew a great guitar player because I couldn't really pull off those solos.
