I think the 3rd headliner is pretty obvious & everyones missed it!
*Never Played Download Before (doubt AC is gona select 3 headline repeat bookings!)
*Have'nt played the UK in donkey's years
*Fit The Classic Rock Tag
*Have A Huge cult following
*They would only ever accept headlining
*Headlined some European Sonispheres last Summer....but dont seem to be contracted to play any Soni's next summer but have announced 1 UK show next year....so are available
*Totally different to SOAD and Linkin Park so tick the variety box section.
*Andy Copping hasnt ruled them out but seems to have ruled out all the other 'headliner' suggestions
....surely it is MANOWAR
...this is what my gut is telling me....and my gut instinct is normally very reliable.....so i think efests can now add them as a rumour...make that strong rumour!
edit. and note i am not a Manowar fanboy, bloody cant stand them myself!
