His backstage stories with Yes are classic.
My favorite is the one about how when they were recording Tales, Jon and Steve started filling the studio with haystacks and farm animal cut outs to get the "environment" they wanted. Which led to lice infecting and ruining some of Wakeman's keyboard equipment. He spent most of his free time during the sessions playing darts and drinking beer.
And of course there's the famous incident when Yes were doing a live show playing the Tales set and Rick ordered some Indian curry on stage, what a guy.
