Monday 12 May Ticket update Due to overwhelming interest in the concert there are no more tickets available. However, because this is a free concert, there may be seats available on the night of the concert. Voucher holders should exchange their Voucher(s) before 7pm on the night of the concert. For those who requested tickets on our form and were unable to get a ticket voucher, Standby Vouchers have been sent out which may be exchanged for any available seats after 7pm on the night of the concert at the Box Office, Door 12. Standby Voucher holders should join the Standby line outside Door 12. At last year's concert all Standby Voucher holders managed to attend the concert. If there are any remaining available seats after all Standby Vouchers have been exchanged, they will be made available on a first come first served basis at the Box Office, Door 12. Ticket requests that came from outside the United Kingdom: Tickets ordered outside the UK will be held at the 'Pick Up' table inside Door 12 from 5.00 pm to 7.00 pm on Monday 19th May. If they have not been collected by 7.00 pm they will be made available to Standby Voucher holders.
