While Murray the K's traditional Easter break shows were a can't miss for young rock and roll enthusiasts, the 1967 event, which featured five shows a day at the RKO Theater from March 25th-April 2nd, proved particularly momentous due to the American debuts of unknown British bands The Cream and The Who. Much has been written about this fabled Easter week of performances on and off stage produced by Murray the K. An extremely rare program considered one of the 'holy grails' of rock concert programs.
