The Mellotron Group

Yesterday I was finally able to see the Classic Artist Moodies DVD.

At around 1 hour into the film, when they’re discussing In Search Of The Lost Chord, we see what looks like footage from

some Mellotron MKI / MKII promo: we the machine cycling, keys moving, the lid sliding in , springs going up and down etc.

Anyone got any idea what the source of this material is and if there’s a full length version anywhere?
