Only recently, their home movies surfaced and were restored.
Composer Peter Vermeersch made a 40-minute selection of scenes and put these to music, to be performed by Flat Earth Society.
I was at the premiere a couple of months ago and it was pretty amazing.
In the meantime, a second and third screening / concert were performed.
But the really good news is that the project got released on DVD.
