Happy Trails - Quicksilver Messenger Service

I guess this is another of my favourite album covers. It doesn't really give you any clue as to the music within. It is mostly guitar based and what we used to call 'stretched.' i.e. Who Do You love is a rambling live cut, lasting for all of the first side with audience contributions. I only knew about this group because in the 1970s, I subscribed to a magazine called ZigZag. It is music of its era.
