you can't sing the blues. [Funny.]
I'm not sure that's a 100% hard-and-fast rule, but it does seem true in my case. One of those things I just have to live with. Perhaps the closest I ever came, if it even might be considered almost somewhat close, was singing Jumping Jack Flash in public once in high school. That was definitely one of the more embarrassing moments of my high school career. A particularly telling aspect of our performance was the fact that the lead guitar line was played on a flute.
