Please don't worry about your own voice -- sing away! I can almost guarantee that your voice is better than you think it is (people today are sort of beat down from an early age into thinking that an imperfect voice is a bad one, which is as wrong as it is unfortunate). Either way, the great thing about singing in a crowd is that the sum of many voices always sounds fine. And perhaps most importantly, singing is good for the soul.
