Has anyone arranged this song for Tuba Christmas?

The third annual Trick or Tuba is happening Sunday, October 25, at 2:30 p.m. at Soderstrom Castle in Peoria Heights, Illinois, overlooking the Illinois River.

We’re bringing together tuba, euphonium, baritone, and sousaphone players for a Halloween concert, and we’re still looking for more musicians to join us! If the registration fee is a barrier, we’ll do our best to find a sponsor.

Free to attend, and Halloween costumes are encouraged.
