You asked for it, and they're finally here (performing for you). Simply right-click (or ctrl-click) on the file you want, then save it to your computer, and it's all yours to listen to for Christmases to come!
Comic 298 - Jolly Happy Jerk
Instrumental "Karaoke" version
Comic 299 - Carol of the WAA
FAST version (this was the original recording speed, but I slowed it down electronically since it made it hard to follow the comic)
Comic 300 - A Simple Request
Original site version
Also, a bonus tidbit--Chris is redoing the drum part for A Simple Request and will be uploading it soon! He's also working on the video.
Have a good holiday break.
