How many songs can you name with 3 or more covers by other famous bands?

Preferably 3 studio versions instead of live versions with only bad quality youtube videos. I have All Along the Watchtower (Jimi Hendrix, The Fratellis, U2) and 21st Century Schizoid Man (Voivod, Ozzy Osbourne, Tool) and am looking for at least 2 more.
