Saw Atomic Rooster at the old Palatine Hotel, Blackpool, along with other greats in the early 70's. All you needed was the entrance money and a couple of Tabs. Played snooker with Hawkwind there too, before they played.
I don't why Rooster drummer Paul Hammond is not rated as one of the best, his skills and originality easily match that of Ward, Bonham, Powell etc, superb drumming, very talented band.
