Songs you didn't know were covers

[Kol]

When I was researching for the latest tournament I found a song that I hadn't realised existed, I had only heard the cover before. This is inspiration for this thread, songs you didn't know were covers for a long time or songs you think most of us won't know are covers. You can also post covers we might not know about assuming the original is the more popular version. Here is mine to start it off

The Lover Speaks - No More "I Love You's"



and the more famous cover by Annie Lennox
