My clever wife found it on Amazon. Turns out to be the Penguin book of American Folk Songs "edited/collected" by Alan Lomax and not Pete Seeger.. In my defence it was a lot of years ago I bought this book.
Anyway I have just ordered a used copy off Amazon, not at $3,000 I hasten to add (yes there is on on there at that price), but it did make me go and look up a bio of Alan Lomax. I thought he was English since my only remembered reference to him was the Alan Lomax Trio on the quadruple album "Electric Muse" where they were playing "Hard Case", a brilliant song.
A very interesting man. Shame he is dead.. I would love to have had a in depth conversation with him.
