In Concert...prolly Jack Riley and Carl WIlson?
Wasn't Jack Reily fired right after Holland? Even if he wasn't, I'm not sure he influenced setlists that much. Around that time, 1972-73, probably Carl, who was producing those albums... and maybe good old Mike?
I read somewhere that Brian (of all people) wasn't happy with the Beach Boys In Concert album. But I don't remember reading why.
