In 1968, John Lennon performed a song from the "White Album" with bandmates from other groups of the era. He band was called "The Dirty Mac" and featured bandmates from The Jimi Hendrix Experience, The Rolling Stones, and Cream, viz., Eric Clapton and Keith Richards. Richards looks normal, amazingly. Also note the man speaking with Lennon during the video intro is, of course, Mick Jagger.
BTW, a "Mac" is British slang for a raincoat.
