There was a great outtake from 15 Big Ones that nobody has mentioned called "Michael Row The Boat Ashore". Mike's lead is nice, Brian's reaching some high notes and it has an interesting and fairly tranquil production.
Somebody finally mentioned this song! Thank you!
This is my favorite unreleased Beach Boys' song of all. Love it. I read somewhere that Al produced it but it is so Brian. The "Sloop John B" intro, the backing track, the "allelujah" backing vocals, and Mike's lead vocal is great. I'm surprised they and/or Brian never resurrected this one.
I am almost certain it's Brian who produced. I think Al's name got mixed in there because it was to be included (for some odd reason) on the 1977 Xmas album. As far as Mony, Mony that is Brian at the end showing how shrill and thin his voice got. Worst covers to me is School Days, and (Remember) Waliking In The Sand. Sorry for the earlier typo.
