what cover versions are better than the original

For example, Mott the Hoople's version of Sweet Jane is the equal if not better than the Velvets. Also, as long as I'm on the Velvets, a one album band called Detroit, fronted by Mitch Ryder, did a version of Rock and Roll that destroys the Velvets original.What are some other examples....this post is not for rock only....
