Oh mem just listen how creatievd these cat's were back then in the early "pro-gresed" music . Simply love all these parts and sudden style or beat chances. Plus wonderful lead vocal by Jon Anderson with nice and solid background harmonies (ala Beach Boys style)
this is an absolute "must be stoned listen to it". do it! my favorite yes song beeing stoned. really.
aim high shoot low. shoot high aim low, whatever, that means I AM HIGH!
