You probably already know but Fast Cars was the last song of the 3rd Encore for Boston 12/04. The Commentary from Bono b4 and after the song to end the show was great. This would be the show you want, not to mention all the hype surrounding the rest of the performance - absolutely amazing.
I highly recommend it, and if you get your hands on it please let me know - mkzoots @ hotmail.
