Helping Heston

It's only taken five years but Jon has finally managed to start a recording ahead of time. It lasts thirty seconds and immeadiately fails. This is followed by an intro section that goes completely out of sequence and one of the most obscure puzzles we've ever done. There are no locks, no keys or codes. All that's needed is the answer to a simple question. What's wrong with Heston?

This episode features Jon, Jamie, Ben and even Jon's wife Sinead providing some piano for the ending.
