Tibet House US Benefit Concert - Carnegie Hall February 26, 2010 in Shows Posted January 9, 2010 · Report reply quote: Originally posted by altered ego: Oh, crap. I bought my John Mayer ticket I think a month or so ago that's scheduled the same night as this benefit concert. I shelled out $95 for it and I'm tearing my hair out right now, praying I can find someone who's willing to swap tickets for his 25/02 concert. Gawd, help me. Send out some positive vibes for me, will ya? Craigslist is your friend.
