My problem with the covers is not that they play one every night, but that they only rotate a small group of them. We've heard 'Stone Cold Crazy', 'So What!', 'Turn The Page', 'Die, Die My Darling', 'Last Caress', 'Breadfan', 'The Wait' and the Motorhead ones enough already.
Play 'Astonomy', 'The Small Hours', 'Sabbra Cadabra', 'It's Electric' etc.
Or, here's a notion, play something that isn't on 'Garage Inc.'.
