They were a great band. I think those deluxe versions and reissues and stuff with all those rarities really cemented that for me. Tons and tons of great songs that he didn't even bother putting on albums. It's astounding. I pretty much really enjoy most songs on Aeroplane, if not pretty much all of them. That's an underrated collection and not just "leftovers" at all.
Btw sorry I am taking so long to get to your song ideas my brother. I feel bad I keep putting it off, but I am just putting together some new gear for recording and setting up a new computer/section for recording lately, so I am just waiting for everything to fall into place and get settled soon. Definitely didn't forget ya!
