Yes, I sing too. People who haven't done it, do not know that it is much more difficult to sing and play guitar at the same time, as to do either by itself.

I used to play and found it difficult to sing and play, too. You have to get to the point of skill that Hendrix did where you and guitar become one and it is merely an extension of you and you of it. When you flow together, then singing is bound to be easier.
