I have had this thread going for some time, and I really should have mentioned that it was put together by Dr Reg Hall in 2017. A good number of the photo's are from his collection. There is also some excellent details upon the singers, and a list of other contributors, from the academic world. There is also an assessment of PK work as a collector. I hope this document is a valuable addition to your library, and that was my motive in posting it. I'm sure that if you only have a passing interest in Traditional Folk song, you will find something to interest you.
