It was the right decision hands down! I think after Robert's son died part of Zeppelin also died. Jimmy health was declining and the ITTOD sessions were a very dark period for Zeppelin. Robert & Jonesy were the only ones who would show up at rehearsals and began writing with each other. Jimmy was a mess. Peter Grant was also declining as a manager. He never should have let things get so out of control. The group wasn't as hungry as they were a few years prior.
