Bruce Hornsby, in a lovely in depth feature at Stereogum marking the 25th anniversary of Bonnie Raitt's 'I Can't Make You Love Me':
I changed the chords around to suit my aesthetic or my style, I guess. I added my voicing to the mix. The way I move through the chords playing harmony … It’s more about moving voices underneath the melody, voices meaning other tones and other notes in the left hand. The left hand moving in harmony with the right hand melody. It’s clearly heard on the record right away.
I've mentioned this song here before and will doubtless do so again.
As the article illustrates, Hornsby's contribution to a song he didn't write makes an already exceptional moment into something people are still covering and writing about 25 years on.
