To be fair,Peter in his "Who am I" didn't bash LZ as he did in the past.Live at Leeds is to this day one of the great live albums. I *think* the dislike of LZ was John and Keith fed up with Peter's -attitude- and wanted to join Page and Jeff(Beck) and form a new band,.....IMHO.
Back to Prince was it : "Different colors in music,like Led Zeppelin."
