Manowar won't ever be an option for Graspop anymore. Graspop organisation bashed Manowar several times already. For example in the introduction text for one band (cant remember which) a couple of years ago they wrote: "you want a band that reminds you of Manowar's music, but without bandmembers who are a bunch of douchebags, go check this band out!". And with the demands Manowar has and after the Hellfest debacle no festival should book them ever again.
