Jazz song, maybe Ramsey Lewis?

[Enigma01]

I'm not sure if this a 'download link', but it is the MIDI file I wrote up in NoteWorthy. It's the main melody line of a popular jazz piece, although it's probably funk/groove, given the deep mellow bass guitar in the beginnings. There a re faint female vocals that I can't make out the words to. Well, here goes:

If given more time, I might be able to remember more, and transcribe it; I'm by no means good at music, though.

Thank you ahead of time.
