Tuba?

I learned to play tuba in high school. I was failing typing, and saw the music director about maybe playing an instrument in the concert band, which rehearsed that period. He said there were not many pieces with guitar, but they could use a tuba. So I learned it. Since I sung rock music, the breath control was easy. I even recorded a song I wrote in high school, using the tuba, and submitted it as part of a project. At Maryland, they kinda recruited me to keep at it, but I haven't played tuba since my sophomore year of college.
