According to trustworthy Graham Coxon Uk forums sources, a DVD of the entire Barbican show from last november is coming out next summer, specifically on july. Apparently, it's going to be released by Transgressive records, which is the current Mr. Coxon label.
Personally, I couldn't be more happy with it, for I attended that show travelling exclusively from Spain to London with a friend. It's a lot special for me, really loved the power acoustic ensemble, that atmosphere created at the Barbican Hall with the music was a special one :) I'm awaiting to find out more details. Stay tuned!
