Two other songs about women from New Orleans from that period:
Steely Dan - Pearl of the Quarter

The Doobie Brothers - Toulouse Street

Sounds like a B side to me.
Kind of related:
The House of the Rising Sun, The Animals and Eric Burdon
This version of Take A Heart (Sorrows/Don Fardon) is great.

2:18 is when the mariachi piece starts!
Wow, surprised I hadn’t heard this before. Cool song.
