Interesting question. Who knows..I always kinda perceived it as them paying attention to what he is saying. especially after GS I kinda have a feeling the other 3 band members are quite protective of Chris. He is also the spokesman and all and I always see them as quietly encouraging him along.That was really funny! Loved it! Btw, is it just me do the guys always seem nervous about what Chris might actually say in interviews (like they'll look at each other)?
