has an insider leaked that GNR will play Mad Cool?Mad Cool festival will have an announcement on monday and apparently GNR will be one of the headliners. So maybe Graspop could also announce them?
Only problem is that Ken19 said on efestivals forum that Rock Werchter will announce last headliner on monday.
Did Graspop and Werchter ever had an announcement on the same day?
