This is a simple little novelty piece written for two trombones (or two euphoniums, two cellos, two bassoons, etc.) with piano accompaniment. The occasion for writing this piece was a fundraiser dinner, with a euphonium, a trombone, and a piano available.
Each trombone takes a turn playing "When the Saints Go Marching In." The piano then gives a little key change, and the second trombone plays "She'll be Coming 'Round the Mountain," with harmony by the first trombone.
This is followed by a duel of partner songs:
Saints with Coming 'Round the Mountain
Saints with Amazing Grace
Saints with The Star-Spangled Banner
The piano then plays "Merrily We Roll Along" in a high register, which is followed by "Good Night Ladies" partnered with Saints. This goes on for a couple of choruses, and everything wraps up with a big finish.
This would be a fun number to end a trombone recital where the student plays with the teacher, or anyplace a couple of trombone players are hanging around with a pianist. All three parts are relatively easy (and easy to memorize), which makes this even more fun to play.
