the ones I can think of are based on the fact
that I was imagining a male/female couple singing
and that brought to mind THE WATER IS WIDE and
Nanci Griffith's GULF COAST HIGHWAY.
perhaps anything for the album "oh Sister" would work.
HELLO STRANGER by Hazel and Alice comes to mind...
or other girl groups:
Hot Soup!
Four Bitchin' Babes
good luck let us know what you find!
