I never met Harry Boardman but in my early days on the folk scene his name was revered. Everyone who came into contact with him spoke well of him On my record shelves I still have his sublime album Trans Pennine - Topic Records - 12TS215 (1971) where he is partnered by Yorkshireman, Dave Hillary. I also still have another Topic album which he curated Deep Lancashire - Topic Records - 12T188 (1968) which were the first recordings by the Oldham Tinkers, Mike Harding and Lea Nicholson.
When I came to Sussex in 1968 Tina and I started a folk club within a few weeks of moving to Brighton. We asked two other singers to join us as resident singers at the club - One was Lea and the other was Mick Jones. Both were Lancastrians and both were at the U. of Sussex. Both spoke highly of the time and effort that Harry had put into teaching them an approach to singing and to song accompaniment.
It would be easy now to forget the effort and enthusiasm of some of these regional pioneers after such a long time. Fortunately, in Harry's case, there is a webpage that details some of his accomplishments.
