Not a concert venue, but my only claim to fame is that I once attended a house party in the Black Country (late 70's) where Robert Plant was drinking beer in the kitchen. Too star-struck to speak to him, but I did stand in that kitchen for a long time. Transpired later that the host & hostess, who I knew via a mutual friend, drank in the same local pub as Mr Plant, invited him on the off chance and were as surprised as the rest of the guests that he actually turned up. Very down to earth guy.
