A quick note about the Real Book: It is not supposed to be played as written. In particular the most famous standards (like Autumn Leaves) just have the essential information. Rhythmic figures often need to be interpreted, or the song will really sound dull. "Bye Bye Blackbird" springs to mind: check the 1958 Miles Davis version and compare it with the real book.
