I think there's a very specific group of people that would like this and most of them are able to replay it by ear, especially once they know what key it's in.

But if you know the chords, and you can correspond a chord to a specific section of the melody, you'll know that the notes are within that scale.

If this is too cumbersome, you might isolate the melody with something like Audacity or another DAW-like tool, look for a wav to midi converter and import the midi in a DAW to see the notes. YMMV.

In any event, if there is no sheet music, note progression or anything like that available, you will need to do some of the work yourself.
