I need a general admission ticket for Take That on 28 June 2008 at Old Trafford. I bought 5 for me and my friends and then my sister said she wanted to come. I made a mistake and booked her for the 27 June! I have Ticketmaster confirmation that I can pass on as proof of purchase. Does anyone want to swap a GA ticket on 28th for my spare on 27th? They have a face value of £45 but we have paid £54.45 inc fees to Ticketmaster. Here's hoping!
