Like I said, the chart I posted is about the original version by Clare Fischer. So there's no such thing as G7 or G7+11 in the 2nd and 4th bar of the head in that recording. However, for the intro and the solo parts, they do play a G9.
You're probably referring to the Art Blakey arrangement of the song, where they play like you said, a G7+11. That version is a pretty straight forward jazz arrangement.
In the original version by Clare Fischer (or any version where he plays), the second chord of the head is a bit more obscur. My guess is that he got the influence of classical Bach music. The voicing there is something like F# (at the bottom), D, A, B. (This is why I've notated it B-7/F#).
But actually adding the notes from the melody (C# F, G#) produces this particular dissonant Bach harmony (in other word, it's basically a F# minor chord with a D diminished chord on top of it.
Looking forward to discuss further this topic, but make sure you listen first the composer's original recording so we are on the same page
