I ordered Hamm's edition of "Heart Songs" but it didn't come in to the store. I'll look into "Yesterdays,…"

My (now retired) thesis advisor said: "… Charles Hamm’s 1983 edition of the 1909 Heart Songs volume. I heartily recommend you obtain a copy. Hamm’s redo should still be in print and, if not, used copies of the Hamm—or the original 1909 ed.—should available from booksellers. I’ve picked up two copies of the 1909 over the years. Best fake book I ever bought!"
