This thread was refreshed by Spam that I deleted, but it was nice to see the thread again. The Randolph-Legman books are real treasures. Volume 1 (Roll Me In Your Arms) is folksongs and music, and Volume 2 Blow the Candle Out) is rhymes and other lore. Both are great books, but I prefer the songs. As Abby points out, Volume 2 has the index, so you need both.
And it seems appropriately inappropriate to have a few dirty songs during Holy Week....
