Chain Reaction of Love is later--from the Paley sessions. I like a couple of tracks from the Sweet Insanity era--"I Do" aka "Do You Have Any Regrets" being at the top of the list--but feel that in general the material is pretty weak and certainly marred by the now-dated production style. "Thank You" AKA "Brian" could've been a really great track if not for the horrifying lyrics. Would be great if Brian one day were to redo that tune with a new lyric.
The 2 you mention are my favorites, but yeah, the lyrics on the latter are awful. Sad that a good melody was wasted on those words.
