Always something wrong

What are known as the Roots albums have mainly been about Elvis but there seems to be a couple on the Beatles which more or less repeat the same versions.Which is because Elvis covered practically every song he recorded even some of the movie songs.
When this came out it was before the BBC Sessions so its the actual covers the Beatles did on their albums.
So its predictable really-the originals by Little Richard,Chuck Berry,the Isley Brothers,the Shirelles etc.
What's not though is why Kansas City is here by Wilbert Harrison-the Beatles covered it from Little Richard's cover which added the "Hey Hey Hey" song.
