Earl's Court
This means they can continue their quest to have Queen + Freddie & John, come full circle with Queen & adam lambert.
Also, it can tie in nicely with releases of old Queen + Freddie & John concerts
I wouldn't see much use for a Houston Texas market... If anything AUSTIN but not houston. Don't think they'd enjoy much like that out there.
Possibly LA... So they could get that damned musical over at the Pantages or something.
