On all versions of this release songs 1 and 2 on the second disc are mixed up, so track 1 (disc 2) really starts with "Theme From Jack Johnson" and "Interlude" is track 2. The song "Interlude" contains a version of the theme from "So What", a track from Davis's Kind of Blue (1959).
This is one of my favourite jazz albums, it flows really nice and shows such great technicality. Just such a fun album to listen too.
