This song by the Brobdingnagian Bards seem more than appropriate for a Friday evening/afternoon… (via) There’s a prequel version, too!
Both songs are available on iTunes: The original is from Brobdingnagian Fairy Tales, and the prequel is on Real Men Wear Kilts.
I believe I’ve seen them at Dragon*Con before. I’m sorry to see that they’re going their separate ways.
