John Entwistle's Isolated Bass Track from The Who's "Won't Get Fooled Again" at Shepperton Studios

Today, we'd like to remember the legendary John "The Ox" Entwistle of the Who, who was born October 9, 1944.

Below, check out some extraordinary footage of Entwistle's isolated bass track from the Who's "Won't Get Fooled Again," as performed May 25, 1978, at the U.K.'sShepperton Studios. Entwistle, who is standing in front of a wall of Sunn cabinets, is playing his Alembic Spyder bass (Dean makes a limited-run version of this bass, the USA John Entwistle Spider)

The performance is from a mini-concert set up by the band for use in The Kids Are Alright, their career-spanning 1979 documentary. It turned out to be the last performance, ever, by the original lineup of the band. Drummer Keith Moon, who is noticeably bloated in the full-band version of the performance below (bottom video), died just a few months later, on September 7, 1978, at age 31 after mixing the alcohol-withdrawal drug Clomethiazole with alcohol.

Sadly, Entwistle died June 27, 2002, at age 57 while the Who were on tour in Las Vegas. The local medical examiner determined that his death was due to a heart attack induced by cocaine.

The next day, the Who's Pete Townshend and Roger Daltrey published a tribute onTownshend's website, saying, "The Ox has left the building; we've lost another great friend."

Regardless of the fact that the band were clearly rusty in May 1978, this footage of "Won't Get Fooled Again" is one of the most exciting and powerful Who performances caught on film. And then there's Daltrey's freaking amazing scream at 7:50. Enjoy!
