2 seated tickets for Lady Gaga at Twickenham Stadium, Sunday 9th September 2012 - good seats ?

Hi I have 2 seated tickets for the above concert, I am unable to go now as we are expecting! North Stand middle, Section M20, Row 66, Seats 121-122. If you want me to post it will be 5 extra on top. I have the tickets in hand. The face value of the tickets was 70 each. I am located in Wixams, just outside of Bedford.
