A lot of the times, we find it to be very pointless, but it's very important for any musician to be able to play guitar (beyond simple three chord progressions) and sing. I think it has a lot to do with confidence, confidence as a player and a person. I think that once we stand in front of a crowd we can't stop thinking about possibly screwing up, and when we have to sing and play at the same time, it can be rather overwhelming. The best advice I can give you is Practice, practice, practice. But also practice feeling comfortable in front of others, start with your (imediate family) then you frirends, and etc...

You'll get it, eventually, as long as you never give up. And "All of The Small Things by Blink, after a while it really starts to get on your nerves. Try singing along to "Spoon Man" by Soundgarden, it's cool!
