I saw Yes only once, in 1983 on the 90125 tour. Great show. Was Squire back to playing his Ric on that tour? I did briefly meet Alan White after the show and he signed my tour book.
He used plenty of basses, depending on the song just like in the 70's. He had the green Mouradian ("Owner Of The Lonely Heart"), the Elektra ("Leave It", "Cinema", "City Of Love"), the 8-string Ranney ("Changes", "Hearts"), Thunderbird (for "Gimme Some Lovin'" and probably for "Our Song") and the Ric ("Hold On", "It Can Happen" plus all the classic old stuff).
