Hi Free Reed, (Is it Neil Wayne?) Thanks for the info. I'll try and track down the Howson's somehow. I remember back in 1979 listening to the Old Hat Band at a festival in Kings Lynn.
They played some lovely old east anglian tunes with the late Billy Bennington and the late Oscar Woods and Reg Reeder on hammer dulcimer.
I think I saw John Howson on a website somewhere and I understand he is still researching east anglian music. Which is strange when you consider that the EFDSS way back in the early 1920's said they were not going to invest in collecting any more folk songs or music because there weren't any left!
