Swap Brighton Concert tickets(2) for Wembley tickets(2)?

[Tonypsb]

Hello everyone,

Me and my ladyfriend were due to see the Pet Shop Boys in Brighton this year but she has recently found out that she has the early stages of breast cancer. She is lucky enough to have caught it early, but still has to have a lumpectomy. This takes place about 5 days before the concert and i don't think she would be upto standing. I have 2 general admission tickets that i would like, if possible to swap with someone who's going to the wembley concert with similar tickets. This date is before her op and would help to take her mind off it. All offers would be considered. I know i can probably sell them, but would rather see the concert if possible. Thanks in advance
