1. What is the difference between the Made in California mix of the 1967 Surfs Up demo and the Smile Sessions mix?
It sounds like some tape glitches were patched up. Other than that, I don't think there are any differences.
2. Where else has the single version of California Saga been released? I'm trying to figure out if I have the single version already in itunes. Is the single version very different from the album version?
The single version is on the Greatest Hits Vol. 3: Best of the Brother Years CD. Brian's vocals are more prominent in the single version, he sings "On my way" after the verses throughout. I think the version on MIC is actually the album version.
3. Is the Lonely Sea version on this boxset different besides having the longer fade?
No, I don't think so.
5. From the Smile Sessions, the vegetables and wind chimes stereo mixes were on the LP in the box set, but not the CDs, right? Heroes Parts 1 and 2 were also only the 7 inch vinyl? And Our Prayer wasn't released on the box set in stereo? Are these the only Smile cuts on the box that weren't previously released on CD/digital?
Heroes and Villains, Parts 1 and 2 were also on the 2CD version of The Smile Sessions. Otherwise, I think you have it covered.
8. What makes this Break Away mix different, and is it vintage? I don't have Hawthorne California, so it's new to me.
Brian sings lead, Carl sings on the single version. There's also a longer tag on this version with additional lyrics.
