You're a lot more odd than I first suspected if speculating on what Gareth Rogers is doing is 'fun'.
His role is clearly a behind the scenes role, and as thus, we won't know the minute details of what he is doing, however, just because we don't know them - that doesn't mean he is doing nothing. Right now, I don't know what Harry Shearer is up to, but I'm not going to assume that he is twiddling his thumbs, all lonely and that.
