While visiting London in October 1966, Jimi dropped in on a Cream show at the Central London Polytechnic.
Rumors had already been circulating about the young flamboyant American guitarist, so when Hendrix boldly asked if he could jam with godlike guitarist Clapton, the band confidently welcomed him to the stage to play "Killing Floor."
They regretted it soon after.
As Jimi shredded through the incredibly difficult song in double time, Clapton dropped his hands and walked off-stage. Despite their first meeting, Hendrix and Clapton became good friends.
Watch what happened:
Just a couple of months later, his solid reputation intact, Jimi returned to the UK on December 29, 1966 to play Britain's Top of the Pops for the first time. The Experience played "Hey Joe" which entered the top 50 UK charts at 38, and the Top 20 R&B singles chart at #11.
Jimi and the band reported to the BBC Lime Grove Studios/Area C at 9.30 a.m. for rehearsals and stayed until 7:30 p.m. to perform “Hey Joe” during the live broadcast. The Breakaways (Gloria George, Barbara Moore and Margaret Stredder) were used for additional background vocals. The Experience were introduced by DJ Simon Dee.
The Show line-up was:
Dave Dee & Dozy Beaky Mick & Tich - Save Me [Repeat Performance]
Wayne Fontana - Pamela Pamela [Performance]
Tom Jones - Green Green Grass Of Home [Repeat Performance]
The Who - Happy Jack [Disc]
The Supremes - You Keep Me Hangin' On [Promo Video]
The Jimi Hendrix Experience - Hey Joe [Performance]
Cream - I Feel Free [Repeat Performance]
The Monkees - I'm A Believer [Promo Video]
Reportedly there is no footage of that performance, but this video was captured near the timeframe and it is pretty darn great:
