I also got this single from my father that I cherish deeply:
Big Bill Broonzy
7" with four tracks,
incl. This Train, Goin' Down the Road and A Shanty In Old Shanty Town
Cant find any reference to it on the net, I'm guessing it should be rare.
Also one by Sidney Bechet, four or so beautiful tracks from 1923 or 1926 on it.
You know what track took me forever to find back, even online? This one:
Nobody Knows the Troubles I've Seen
Its used in Marcel Ophuls' documentary on journalists in the Bosnian war named after it. I didnt hear it for years until someone had it on a tape in the cafe I worked at, and a few years later I went looking again, in the library and online, and found lots of Robeson and different versions of "Nobody Knows" (incl a beautiful one by Marian Anderson), but not his.
In the end I found an album (vinyl) of his songs with the track on it in the "all for 3 euro" box at Latei, the Amsterdam cafe-cum-eightiesretro-shop. Cute buy
it was too: hidden inside the cover, it turned out, was sheets of typemachine-written papers on which someone, some time, had typed out the lyrics to all the songs...
