quote from the obituary
Publicity wasn’t his style; his first love was the music.

It probably isn’t widely known that Dave Bulmer also acquired the rights to material from a number of small record labels who had recorded other aspects of British culture including various recordings of Brass Bands. Dave wasn’t a collector in the sense of a Cecil Sharp or a Peter Kennedy, but he had amassed a vast amount of material in his stores."
The music HAS BEEN in effect lost, it has not been released for 40 years. I made a recording with The New Mexborough English Concertina Quartet in 1986 this has been acquired by Dave Bulmer and is unreleased . I understand that music by NicJones an old man who can no longer play is also unreleased and owned by the Bulmer Family.
if his first love was the music why is this material unreleased.
