by Richie Unterberger   Although unknown to the English-speaking market, Cuby & the Blizzards have been one of Holland's top blues bands since the mid-'60s. Some of their early singles had a beat/punk orientation, particularly "Stumble & Fall" and "Your Body Not Your Soul," both of which would be reissued on various Dutch beat compilations a few decades later. They quickly settled into a straighter blues groove, however. Their claims to fame in the larger rock/pop world are that they briefly backed Van Morrison in the gap between his departure from Them and the beginning of his solo career, although details of the association remain murky; also, at one point lead guitarist Eelco Gelling was asked to join John Mayall's Bluebreakers, although he declined.
