I get this one often so I'll chime in.
As a young man, I was required to learn how to play an instrument by my parents. I'm from a family of 11 children so renting an instrument from a shop was out of the question. Borrowing one from the school was the only option and two of my other brothers played the Euphonium. It just turned out that I was good at it... REALLY good at it... like nationally known good. During my middle school years I began aspiring to be a professional musician and later in High school started wanting my own horn. Looking at professional horns, There are basically two options: Besson and Willson. After trying them both out, I fell in love with the Willson and at that time, Juno email became a thing. Oh dial-up email... So, I picked the name Willsonman for my email account and it has stayed with me ever since.
I'll note that nearly EVERYONE gets the spelling wrong, using only one "L" in their spelling. While my days of premier performances are long gone, I do still play on occasion. I'm classically trained so never expect anything too entertaining from me, unless you enjoy Bach.
So now you know...
