I dont think you being dumb at all. I have no idea what the guy on the record shouts at that point. Possibly "footballs" but maybe not.The logical answer is clearly "fog" but youre meant o figure that out youself. Perhaps in live performance they shouted out any old rubbish at that point? I would have a guess at a slightly garbled "footballs" but others might have other theories.
    God's words to us are not always clearly undertandable, and so it is with Donegan. We have to make efforts youselves.
