that's never stopped me... I always figured you say you play blues guitar, then you play blues guitar and gives 'em what you gots. 
I also always figured I'm a ready excuse for everyone, as in "hell, if he can post that, I can post this!"
I must admit to have started singing (sic) when I play as it makes the whole thing hang together so, OKeh point taken I'll be brave and do something with a vocal
I asked myself which took more spheres, to ad lib all that stuff on the juke or sing a song, and concluded if I could do the juke then I must be able to do song
