I do understand the frustration some people feel when singers put some kind of new interpretation on a standard. This is one of my personal favorites, and I was so glad to run into this version by 2 rock singers who do right by it.
I mean, it has a melody. It has lyrics.
Original lyrics. They were probably never completely impossible to find, but the vast majority of popular singers did a version with the lyrics altered. One commenter on this video actually thinks the nice versions she's always heard were the real thing.
Here it is, original lyrics (mostly) restored by those Great Traditionalists, Rod Stewart and Cher!
And Happy Valentines Day.
