Whilst in the USA there was Martin and the Coys - avail. on Amazon.
And on the Cultural Equity site there is The Chisholm Trail - intended to give the British public an idea as to life in the USA. FGS.
On YouTube there is the Lincoln Lonesome Train Contata from 78s - starring Burl Ives.
And there is the newly re-discovered Man Who Went to War - with scripts - starring Paul Robeson - at the LOC site (unavailable to the public). Apparently PhDs have been granted for analysing this short programme. But academia have claimed as their own and the LOC refuses all access.
BTW all the above was sponsored by the BBC and likely not actually aired in the USA.
