CCR(if his wife/manager tells John to do it he will)
Fleetwood Mac(w/ Christine)
Halen(if DLR can sing)
Beach Boys(wrong demographic)
WHITE STRIPES(Jack in blue outfit = subheadliner, Jack in red outfit = headliner)
David Gilmour(with Waters/Mason?) IMO, Wall tour is done after Europe in summer 2013 and it never did a festival.
DOORS(all 3, with guest vocalists)
Missy Elliot(w/ several guests)
Will Radiohead ever headline again?
I am fully aware some of these are too "pop" and a couple are probably subs.
