Okay, Jon Anderson will be represented several times - Yes, ABWH, & work with Vangelis.
However, he has to have a solo effort as well. That has to be:
Olias of Sunhillow
But which cut?
Moon Ra/ Chord / Song of Sea
or
QoQuaQ En Transic / Naon / Transic To
or
Ocean Song / Meeting
I'd have to sneak the whole thing on myself.
But alas, someone must choose.
