I musta missed this thread before so if it's not too late to throw another 2 cents worth in I will...

As someone allready mentioned... Learn the song by talkin' it rather thahn singin' it with then geetar... Reember, a good song is first a good story...

My only other piece of advice is have the music so down that you don't have to think about it... If you can just trust yer hands to do the rightm thing that will free you up to spend yer energy deliverying the story the way you would like it to be delivered to you if it were another musican singin' it to you...
