Derivation of a Beautiful Piano Intro Solo?

This question has been discussed at great length in another forum, but no one knows the answer. I’m hoping that the more sophisticated, experienced jazz and classical fans here might know the answer. The opening (intro) piano solo on Bruce Springsteen’s “New York City Serenade” (from the album The Wild, the Innocent, and the E Street Shuffle) is gorgeous (IMHO, as a fan of classical, jazz, and a lot of other music). I also know that it is somewhat derivative, because I remember hearing at least part of it on – I believe – a Charles Mingus composition. Someone in the other forum believes that it is derived from some unknown classical composition (of course, maybe Mingus used a classical piece as a starting point for his piece).

Does anyone know the derivation of this beautiful music ? Thanks !
