I eventually came to the conclusion that Brian was actually right, 15BO really should have been a cover album.
Although I kind of assume that the only reason he got to do whatever the %*$& he wanted on Love You was because he agreed to play ball with 15 Big Ones.
I will throw this challenge out to the other nerds out there: resequence 15BO as a 12-15 song cover album. You can even retrieve crap like Battle Hymn Of The Republic if you want. There is a good list here of all the contenders, and you can use May 1976 as a cutoff for making it onto the album.
https://en.wikipedia.org/wiki/List_of_unreleased_songs_recorded_by_the_Beach_BoysAgreed. Release covers album first, and after half a year or so of blank, release next album of original materials- in Love You style. That would have worked both artistically and commercially more, considering oldies stuff was a big thing at that time and Brian's arrangement was not good enough to deal with Love You-y songs like That Same Song or Back Home (with the exception of Had to Phone Ya) at the recording of 15 Big Ones.
Speaking for alternate covers album, I actually have made an alternate 15 Big Ones album of mainly covers, entitled
Rock And Roll Music.
1. Rock And Roll Music (2013 MiC mix)
2. Come Go with Me (I should've gone with the 'earlier version', but I went with MIU version here)
3. Shake, Rattle and Roll
4. A Casual Look
5. You've Lost That Lovin' Feelin' (2013 MiC mix)
6. Sherry She Needs Me (2013 MiC mix)
7. Shortenin' Bread (Early version intended to be included on Adult/Child)
8. On Broadway
9. Peggy Sue (Same as MIU mix)
10. Talk to Me
11. In the Still of the Night
12. Just Once in My Life
Look, isn't it a pretty cool album?
You know, Sherry She Needs Me was written by Brian, but having been in the vaults for more than ten years, it must have been something like a cover more than a original brand-new song.
Sea Cruise would be a good inclusion, just replace the song you like the least with Sea Cruise. On the playlist, it's 'Doo-Wop Music' more than Rock and Roll Music.
