I agree its hard to go on without Glenn Frey. Can you imagine if Don Felder came back for the tour though? That is the only way I see them going on. Then again, Fleetwood Mac went on without Lindsey and NO ONE thought that was possible. The Mac even rolled on without Christine.
If the big final Mac tour is pushed til next year I think its a real possibility of a Buckhingham/McVie tour. And if it happens, I am prepared to spend $1000 for a front row seat
