Well, my screen name says it all: Eupher.
I played the euphonium, trombone, and really bad trumpet throughout my Army career (except the first enlistment), eventually retiring as a player, brass group leader, platoon sergeant, sometimes conductor, and all-round military band geek. I retired 13 years ago.
After retirement, I continued to play and still do today. Got into British-style brass bands with a vengeance having been principal euphonium in two brass bands, but I've played in all manner of symphonic wind bands, small brass ensembles, symphonic orchestras (on tenor and bass trombone), big bands, aka "swing", and even played in reading sessions with a gaggle of violas and cellos.
