What is the B-side of "Hey Jude"?

It’s “Revolution.” That 1968 single is one of the most famous two-siders in rock history — “Hey Jude” is the seven-minute singalong epic, and “Revolution” is the snarling, distorted take on the protest movement. There are two versions: the fast, fuzzy one on the single (this B-side) and the slower, bluesier one on The White Album. The single version hits harder.
