All songs must be "loosely based" on well-known songs, but with lyrics that are somehow related to TSS/YoB/the stuff we do around here. No straight covers, unless you fancy taking on the lawyers

Do the song in whatever style you want, so make it interesting. Dev's doing a gothic version of Beeman to follow up on my sweetly acoustic version. Use your imagination.
That's about it, really. Let's think of some famous songs, change the lyrics so they're suitably stupid and get recording!
