I remember the radio interview...." I wept..I honestly wept"

Good info-but does anyone know what Percy thought about the delivery of Stairway as an instrumental?

Post Zeppelin early 80's Jimmy played STH as an instrumental at the ARMS gigs, Ive seen very little of Roberts opinion of the versions. That must have been a conflict because at the time he was constructing his solo career and avoiding the past at all costs. When he first heard it and what was his reaction?
