I’m close to 100% sure that this forum has a cover song thread, but… my search skills, honed on google, yahoo & bing are defeated by Discord.
Anyway. Here is a lovely version of the Beatles, covered by a great dub/reggae band, the Easy Star All Stars.
For something a little different, here is my favourite Beatles cover in a very, very different style, " Happiness is a Warm Gun" by late 90s alt band, The Breeders.
