Open Mic Night

Ok, im steping out of my shell,my best friend shanelle and i are going to sing the song "Lean on me" by Mitchal Mosso. Shanelle thinks we can do it bt i'm not so sure about that cause i cant sing very good!I'm so worried that im gonna frezze up on stage and make shanelle look stupid :-( ! I guess that i will just have to pray and practice alot to get over my fear.If you have any advice,please dont hold back!
