4 October 2011: Another SCOOP on regularrocker.nl! The earliest concert date thus far was traced back (another feat by Martin Stassen) to Friday 6 July 1979--in Paradiso, Amsterdam, of all places! It figures what bluff it must have taken to put a band on the bill that didn't even have a record out then. Friday is the main out-going night of the week, Paradiso was and is a major concert venue, all the great bands of the earth have played there, including Judas Priest, Ian Gillan, Thin Lizzy--you name it.
