That must have been an amazing concert! I never got to see Yes or Wakeman.Is Rick Wakemen playing the piano on Morning Has Broken? He is one of the few foreign artists I have seen perform live! I saw Journey To The Center Of The Earth. Ok, now that I have googled I see that Cat Stevens released his song in 1971 and Billy Joel in 1973. It does sound similar!
I'm giving it to Rick!
