Blew their minds with a song about bears

There was a battle-of-the-bands type contest going on between a rock band of Metallica-grade self-importance, and us (me and Kevin S and maybe Ray).

The Metallickesque band had just made an earnest, rocky song, and it was our turn to create a song to challenge it. We ended up copping the song structure from their song and changing it into an inane lounge song.

Kevin S wrote the words, and as we played the song for the other band, in like a backstage hangout room, written lyrics magically unfurled on one side of my field of vision, as though it were on TV.

The other band was dumbfounded as we played. I worked out some kind of chord/bass progression on the left (chordy) side of an accordion (though the sound coming out sounded like a perc/rotary organ).

It was in B flat. The words were kind of like:
1 Prose. x . . . . . . . 3b 3b 3b 2 1 Rock music history, Who-knows. x . . . . . . . It's such a mystery. Bears. [Something about bears..] Bears. [etc.]

Of course I probably did some random post-awakening edits while trying to piece it back together, but it was to that effect.
