My alt. tracklisting tries to combine the album into "light" and "heavy" sides--meaning lyrically light and heavy, kinda like "Today" (although it works better with Today because the "light" songs are so upbeat and the "heavy" songs are so mellow!). The big difference is just subtracting "Think About the Days" and "Shelter" from the first half and having them open the second half instead. The only other change was switching the order of Isn't It Time and the title track--just thought that Isn't It Time worked better as an opening track, plus it has that "reunion" theme going on.
The danger here is getting an overload of nostalgia and "fun in the sun" on the first side, and having the second side sound like a Brian solo album with the Beach Boys guesting on vocals. But actually I really like how it works--"Daybreak," for example, sounds really nice after "Private Life," and the six songs on "side two" sound really terrific together--like half of a genuinely great Beach Boys album. Plus Al's vocals on "Think About the Days" and "From Here to Back Again" help make it less Brian-centric.
All in all, it results in an album with two really distinctly different "sides," and that for me works better than the official tracklist. I definitely like the second half better, but I actually like the weaker "light" songs like "Spring Vacation" and "Beaches in Mind" more when they are all together--you take them for what they are and then get on to the serious stuff.
