If I could pick any band, past or present, for my festival, the lineup would look like this:
Jimi Hendrix Experience
Stevie Ray Vaughn
The Who (classic lineup)
Led Zepplin (with John Bonham of course)
Ramones (original line-up)
The Clash
The Toadies
Bad Brains (original line-up)
Living Colour
Bruce Springsteen (Born to Run era E Street Band)
Foo Fighters
I know that's more than five but it's the smallest I could whittle it down to
