Hello Doug Bennett,
Thanks for the information about John Allison.   I wonder if
you have any more detail about John Allison's life, marriage,
birth/death dates. He seemed to "disappear" from the 'folk' scene,
wondered if he did concerts or other public performances (there seem
to be a number of radio appearances).
Also, details of the geneology.
Dick Greenhaus provided the information that his papers
are a special collection at the NYPL R&H collection - I'd like to go through that if/when I have time, and if it can be arranged - particularly to document the extant recordings (not included in my listing previously posted).
The only concert reference I found was the 1941 Cavalcade of Songs
at Town Hall - would be quite interesting if it was recorded.
If you wish to PM me, I'll send my e-mail address.
Thanks again!
Best wishes, Thomas.
