Deep Purple Mark 3 in late July 1974. The early cracks associated with such massive fame were beginning to show : "By this time Glenn had started insisting on having more vocal duties. Since I was regarded as the diplomat, it was my job to calm him down, but he was beginning to complain a lot and it gradually became a bigger and bigger problem. David, of course, pointed out quite correctly that he had been hired as the group's singer. You couldn't argue with that." Jon Lord | Deep Purple Classic
