Some of ya'll need to realize that Harry didn't cover this song to one up the original or make a better version. That was 100% not his intention going in to cover this song. He loves Fleetwood Mac and he has said on several occasions that Stevie Nicks is on of his biggest inspirations. Ever stop to consider that maybe he covered the song because he just wanted to sing a song he loved in tribute to a band that means a lot to him?
