Hi Chalky,
I think we may be getting mixed up. The John Bollen I knew in the late 60s/early 70s was from Skipton/Earby area and was a pal of Franny O'Brien, Les Cokell etc and used to come to Lord Jim's in huddersfield before we used to travel over to the wheel. He introduced us to Dave Godin who he met in London whilst at art college and introduced Dave to us northerners. Dave visited Lord Jim's and wrote about it in blues and soul. Googling john bollen, it comes up with a furniture design business in Skipton and one of the pictures does look like an older version of the John Bollen I knew back in the day!
Perhaps someone on here in the Skipton area can confirm?
