WHEAN A WOMAN LOVES A MAN - Free Jazz Leadsheet
It appears the title “whean a woman loves a man” may contain a typo or mis‑spelling (potentially meant to be “when a woman loves a man”), because I did not find credible documentation of a jazz song under that exact spelling.
Given the ambiguity, no reliable composer attribution, first recording, or standard version could be confidently identified.
If you have additional context (such as alternate spellings or known artists), I can attempt to trace its history more precisely.
