As to Surfer Girl, I have a record with the version that was recorded at Hite Morgan's, and on Candix, but that version has a weird section on it, and maybe Brian was still experimenting with it. On each verse, take the first for example - when they sing "all undone," the chords go from G major to g minor. Now on the recording that was a hit, the bass stays on the g note, but on my Candix recording it goes up to B- flat (the 3rd of g minor.) Although I didn't like the sound, it's interesting to see that Brian was already experimenting with playing non-root notes on the bass.
I'm suprised that Usher wrote the music for Lonely Sea. It just has that haunting melancholy Brian sound in the melody. Just goes to show, that I can't trust my ears anymore.
It sounds un-Brian-like to me. More like Usher's style of writing a la "Sacramento".
