Great Vid!
(Re the Beatles) I assumed you WERE going to link to that Video of Paul demoing one to an interested interviewer, as that is the ONLY video I've ever seen of a Mellotron being played (he did snatches from Strawberry Fields if I remember correctly)
Oh, and in the comments below (in the link) I agree with the 4th poster:
"I want every video I see on the web from now on to end with the final frame from this."
