I did that first thing when searching for videos of the song, but I wanted to cover my bases and be sure. I haven't been able to watch any of the videos because I'm poor and on dial-up.
Q5: Is this song one of the following: a post-demo song with more bells & whistles, or a pre-bells-'n-whistle demo of another song?
A5: Nope.
These have all been fantastic questions!
