Rock Band vs. Elves

Elfs Rule apparently is the name of our Elf's rock band!  It makes sense.  Why else graphiti that all over the place...self expression and PROMOTION!  Today our elf and her friends stopped over for a gig.  Luckily, they did a good job of keeping it quiet...or else we'd have all had a very long night.  Apparently, they play carols.  Who'd have guessed?
