You don't need a foot to sing, but you do need a voice. Colds affects voices. I wouldn't mind if Justin Bieber lip sinks his concert. I'm not going either way.
Chester jumps around and really gets active when he sings. He made it through three or four concerts before a doctor told him he had to stop or he would permanently damage his foot.
I can't stop giggling now because in 2011 they released a Meteora demo called 'Broken Foot' for the LPUnderground members, and your comment just made me think of that.
