I think some decent cover version that don't stick to reproducing the original are:
Without You - Harry Nilsson
Love Hurts - Nazareth
After the Goldrush - Prelude
Working Class Hero - Marianne Faithfull
The In Crowd - Bryan Ferry
Famous Blue Raincoat - Tori Amos
Chords of Fame - Marianne Faithfull
Dancing in the Dark - Big Daddy
The Wind of Keltia - Shusha Guppy
Tainted Love - Softcell
I also remember hearing a superb impassioned slow tempo version of Joe South's Games People Play with female vocals sometime in the late 80s / early 90s. I don't know who sang it, but I remember much preferring it to Joe South's original
