Ticket Swap ?

Hey, can anyone here help me at all ?

I have a pair of Gold Circle tickets ( or will have when TicketMaster send them ) for Milton Keynes Bowl on Saturday 10th June but need to swap them for a pair of Gold Circle tickets for the gig at Coventry on 7th June.
If anyone can help me, please e-mail me on either ian.jones1999@hotmail.co.uk or ian.jones2@insolvency.gsi.gov.uk.

Keep on truckin' dudes.
