Gee, doesn't ANYBODY remember writing Lonely Days?

Apart from the usual, I mean.

I just broke down and saw "The Beach Boys" live for the first time since 1986 (they were playing 15 minutes from my house and tix were $15). I thought I pretty much knew what to expect, but I was amazed by what occured: Mike didn't say a single word the whole night (Bruce played M.C), he didn't sing ANY lead vocals, and the very few vocal parts he attempted...well, he made Brian sound like Pavarotti. I mean his voice was gone. He was miming the lyrics the whole show, with all his vocals covered by one of the nameless, faceless back up guys.  This was totally different from Foskett doubling Brian's leads....Mike was essentially lip-syncing. I never though I'd come away from the concert wishing for more Mike Love banter, but I swear he was basically invisible.

Pardon my ignorance if this has been covered before, but I don't really follow the Mike and Bruce show and am not really up on them.

My question to anyone who's seen the show lately: is this standard operating procedure now, did he just have a bad day (laryngitis or some such), or is there something physically wrong with the guy?
