Hey look! It's the Beatles singing "Stairway to Heaven". ('Tubery, naturally.)
What a brilliant arrangement. I don't think I can ever listen to IWHYH or STH the same way again. The lovely guitar fills over "And when I touch you..." sound EXACTLY right over the other song's verse. I also loved the way they (i.e. The Beatnix) have used some Beatles' trademark chord changes, especially at the very end.
