Just realised I forgot to mention that they played in Rotterdam a few days before or after The Hague. I saw them in Rotterdam and only have a vivid memory of them playing Green Manalishi, and seeing little Jeremy hidden behind his huge slide guitar and also playing the piano. Can't recall the songs they played.
I moved to a town called Groningen in 1971. People over here told me about them playing at the "Korenbeurs". The stage manager shut down the "electricical" (as Lisa Douglas from Green Acres would say) because of either the noise or the fact that at 24.00 the place had to shut down.
I'd have to ask about the reason.
