The Smiley Smile Message Board

So I know that Carl and Dennis make few appearances on MIU, so were all the vocals supplied by Brian, Al, and Mike or where there other vocalists?

That's an interesting question, but I'm afraid I can't provide you an answer.  It could be that no one in our community can. It could be that such questions are of little interest to the folks who post here.  With the exception of a subset of people who obsess over the possibilities/permutations of "Smile", relatively little attention is being paid to the music.

The video for "Mike Come Back to L.A." shows various band members (Billy Hinsche or Bobby Figueroa, I forget which, I think Billy) singing along.  Granted, that was an "all hands on deck" kind of singalong but it's likely that a couple of the sidemen did uncredited vocals.

It has been awhile since I watched that "Our Team" documentary, but I recall that Rocky Pamplin is one of the people seen (presumably) recording backing vocals during "Mike Come Back to the LA", and my recollection is that he is shown singing the prominent "come back home" part of those backing vocals on presumably the chorus of the song.

Dennis is clearly audible on "Hey Little Tomboy" (and of course "My Diane"), but not sure where I can hear him elsewhere. Sounds a lot like Carl in parts of "Wontcha Come Out Tonight".

But like "Sail On Sailor" and others before and after MIU, I suspect we're hearing lots of non-BB voices in the mix.

Carl is also very audible on bg vocals for Peggy Sue... which could have been cut at MIU or during sweetening sessions the following year.  These backgrounds are not present on the '76 15 Big Ones version of the song.  I also hear him on She's Got Rhythm.

Peggy Sue and its Christmas companion have Al and Carl all over the harmonies. I'm guessing Ron Altbach is on the album as well.

I'm usually pretty good at picking out the core 6 Beach Boy vocalists in the mix, but this album, more than any, has me saying "Who the heck is that singing?"

Like who's doing the weird accented double-tracked "come come-a come-a come out come out tonight" in the intro to Wontcha Come Out Tonight? I'm guessing Al and/or Brian?   Or at 01:48 the gently falsetto "Little Girl won't you come"

To me that's clearly Al on the come come come out tonight part, though his voice is a bit distorted. And Brian I think on the other part

That is correct to the best of my knowledge

I think Pamplin might be one of the "off" voices on some of those tracks.

Here's a quick screencap from YouTube of the "Mike Come Back to LA" segment from the "Our Team" documentary where Pamplin is seen doing backing vocals along Brian and others (I think Billy Hinsche and Al are shown in this segment as well). No, it's not Huey Lewis.

He looks like Bert from Sesame Street in the clip
