I'm actually 75% completed writing a song parody (or "filksong", if you prefer) tentatively called "Shoot Me Axalon Down, 'Bot", which -- as you might guess -- uses the tune to "Tie Me Kangaroo Down, Sport"; I only need to write up two more verses. What I'm thinking about doing is, if our BWInt-&-Hangar Alliance at BotCon gets a chance to meet up with Scott when it's convenient (as in, not holding up autograph lines or distracting him from things when he's scheduled to get to a panel room), we could sing this parody to him for his birthday gift from us.
As it stands now, I've finished writing the refrain (which I want to be done in multi-part harmony, just like the actual "Kangaroo" song) and five out of the seven verses; in four of those completed verses, each of them represents one of Scott's characters in BW. An option I'm thinking about, should enough people feel brave enough to do it, is possibly having a few of us do solo verses, ideally fitting with a favorite character (i.e. Sapphire singing Rattrap's verse, Sinead on Dinobot's verse, etc.). And I might need one of us to do the bassline, since it will be a cappela.
And to really make this work even better... the wobbleboard. Because (a) the template for this song is from Australia, and (b) so is Scott.

Depending on how things can work during the BotCon weekend, we may need to sneak in a few short practices once we get together (at least, those of us who'd be willing to be part of this goofy little thing). If anyone's got a comment, feel free to fire away.
