Bruce,Re "Inferno" collection, far as I know there's still no online or printed index or publication. If you do a "f" search at LC on "Inferno" you get the general ref & cite numbers & general contents (all the songs in Inferno are simply outtakes from his general collections & so indicated.)
I did manage to scarf the entire "Inferno" collection, however, as xerox of the typescript. It took two years and many money but I have it. All I've actually done with it is learn a few songs and pass a few appropriate bawdy samples to sea song (Hugh Williamson) or hobo collectors.
There's a typed Contents (it should be online by now but I don't know) and I did scan it & OCR it so I can refer & sent the titles file if you like. There's no ref to "rising" or "sun" but titles are not always as they seem, are they?
Should this be a separate thread?
