The Dirty Mac was the ultimate supergroup, featuring John Lennon, Keith Richards, Eric Clapton, and Mitch Mitchell (the supernaturally gifted drummer from The Jimi Hendrix Experience). They only came together for one show, a TV special called The Rolling Stones’ Rock & Roll Circus, which never aired, presumably because many of the acts—like Jethro Tull, Taj Mahal, The Who, and especially The Dirty Mac—upstaged the Stones themselves.
Anyhow, The Dirty Mac played a Beatles song, "Yer Blues," and they killed, they were awesome, but then they launched into another number called "Whole Lotta Yoko" and you can see where this is going, can’t you?
Press play. Listen. Starts off great, doesn’t it? And then they introduce a violin into the mix—not bad at all, eh? But wait, wait for it, wait for it—there. Hear that sound? Does it sounds like an alley cat having its guts pulled out? Yep. That’s Yoko Ono's contribution. She got to hang out with the coolest band in the world, and she fucking ruined it. Of course, that’s arguably what she did to The Beatles, so we should’ve seen this coming.
