Puppetmaster, If you want the monsters of rock then you will probably get it at Milton Keynes, same as last year. It was a good line up, with Purple, journey, Ted Nugent etc on the bill. As for the Download, Metallica where worth the admission price alone for me, last year though - CLASS!
My perfect line up - Black Sabbath
Tool
Metallica
Judas Priest
Wolfmother
Papa Roach
Whitesnake (something for the ladies).
