Mellotronists

....and another thing about Pinder and the MKII in 1969.  I don't 
recall seeing or hearing a lot of 'Tron tuning between songs.

Genesis/Banks, on the other hand would always be tuning, detuning, 
retuning and fine tuning (and giving up) between songs.
I am sure the reason that Gabriel would go on and on and on and ON 
telling his silly stories, was to allow Banks time to NOT tune the 
M400.  There are bootlegs from the Selling England tour with 
endless "Gabriel Gab" and endless choir tuning in the background.

Fripp was right....  "Tuning a mellotron doesn't".  He always had a 
way with words.
