Since you brought it up a related item - indices of songs to most fakebooks
1) a master index of Real Book 1, 2, The New Real Book (Sher Music) 1,2,3, and the Standards Real Book

(there is a PDF link at top of that page), and
2) Then three is the on-line searchable index of ALL (except the OP listed one)
https://www.seventhstring.com/fbindex.htmlso if you need the basics of almost any tune, mainly standards and jazz, you can probably find which book to look in. Just remember FB's have mistakes and sometimes there are much better chords, chord substitutions and extensions ("color") than given in the FB.
