Hi there,
I have two spare tickets to the Black Keys concert at the London O2 this coming Thursday, 13th December. The tickets are in a great location in Block/Section 403, Row A (i.e. Upper Level, Front Row). Selling them for face value, which is £35 (includes booking fee).
Drop me an email if interested. I have the tickets in hand and can meet in Old Street or Liverpool Street over the coming week.
Cheers
