Roland is also the main character in one of my favorite series of books by Stephen King called The Dark Tower and that character is partially based on Charlemagne's Roland.
The Ophir (replacing "Oh, For" in the poem) is from the Ophir Prison Marching Kazoo Band and Temperance Society, LMTD in which I play trumpet. You will be hearing more about Ophir in a few weeks since we will be playing at the Sacramento Jazz Jubilee over Memorial Day weekend.
Ophir has been known to play load and I also enjoy drum corps which is very load so the "blast of the dread horn" applies here as well. I think my wife probably thinks along the dread horn train of thought whenever I practice.
Hopefully you haven't left yet. I will try to make future posts a bit more interesting.
