Nah, unless the extras are amazing, there's no point as I taped the london and Philly gigs on the bbc, which were interspersed with highlights from the other shows, so I'll just transfer them onto DVD myself.
Call me a tight fisted bastard if you like - you're probably right!
Pink Floyd was the only band that interested me at the london one, and i downloaded their performance (best band ever), and the rest was mostly shit. I dont know about the other concerts, but im guessing they are 90-95% shite.
