The Real Book is organized alphabetically, but if you're looking for this tune in the C's, you'll be very frustrated as it appears right between "Lucky Southern" and "Lullaby of Birdland"; neither of which, you'll notice, begin with "C". Bear in mind that this is the same book that puts A Call For A Demons on the very first page (under "A" for A Call For All Demons).
