"Thank You" - Chris Cornell
OR
"We Are Man and Wife" - Michelle Featherstone (VERY beautiful song)
My absolute favourite male singer, Chris Cornell, did a cover the Led Zepplin song Thank You.
I had never realized what a beautiful song it was until I heard the version Chris did.
The only bummer is he never recorded in a studio, so it's a live version. It's still wonderfully done, but you can hear some clapping, and cheering at the end. I still may use it though.
