I would love Led Zeppelin too, but it's very difficult.
As venues, there are Wembley, Wimbledon (must visit, for the female tennis players, lol), Oasis' legendary Earls Court, and even, as you probably know, United Old Trafford in Manchester (but I would avoid that, if not for winning the derby 1-6 with Mario Balotelli ;).
You also already know that Liam's Beady Eye are only playing festivals this year (in the summer), and Noel Gallagher is around during the summer, so they will probably be added to the Olympic Games shows.
More info soon.
Hello (it's good to be back) @ Earls Court 1995, life is an Olympic Game we play :)
