The double-Tron can be seen if you look real closely on LP
cover of "Journey To The Centre Of The Earth" ,released in the USA
in early 1973. 6-Wives was released sometime in summer 1973.
Perhaps those two machines were those destined to be siamesed
together with facing flywheels joined with sprrrrings.
The Wake-O-Tron can also be seen and heard on the DVD, "Rick Wakeman - Legends of Rock", containing material from "6 Wives" and "Journey". It sounds a helluva lot better than "vocalists" Holt and Pickford-Hopkins.
