I also thought Rick Wakeman’s Journey to the Center of the Earth would be a contender.
BTW, the only two albums I bought twice because I wore the first one out were:
Wakeman - Six wives of henry the 8th
Alice Cooper - Billion Dollar Babies
Yeah. Don’t ask...
Bit of Trivia- did you know Wakeman played keyboards on Al Stewart's Orange? Stewart seemed to work with everyone- he had Jimmy Page play lead guitar on Love Chronicles and Tori Amos did backing vocals on Last Days of the Century.
