Might be worth a call to reservations. Even if they charge you £15 to cancel, and it's taken off the amount you get back rather than the ticket fee before refunds, it could give you a tenner in your pocket.

If the cost of cancelling is more than the £60 (don't think it is, think HIDDY is right, the £60 is a change fee), you can tell them you'll be a no show, which would be a nice thing to do.
