Paul McCartney

In this clip Paul can be seen using a Psychedelic painted Knight Piano. He has been using this piano since 1989. In the early 00's Paul started to use a psychedelic painted Kurzweil PC2x instead of his Knight piano. In 2010 Paul went back to using his old Knight Piano again.

Paul was filmed playing it in the Beatle movie "Let It Be".

It belonge to Abbey Road Studios and was used on several Beatles recordings.

This is McCartneys personal piano located in his music room in London. He had it painted by pop artists Douglas Binder and Dudley Edwards in 1967. He used it for writing many of the songs on Sgt Peppers.

“I remember the first time I first saw a photo of their painted car in the Sunday Times Magazine and I thought it was really cool. I told them “I’ve got a little piano I’d like you to decorate in that same style”… It became my psychedelic piano which I wrote a lot of songs on, including “Sgt. Pepper’s Lonely Hearts Club Band”, “Fixing A Hole”, and “Hey Jude”. It’s in its rightful place in my music room in London.”

On Paul's official artist page on the Yamaha site they write "First came The Beatles, and then, Wings. Today, it's just Paul McCartney solo. Paul has been tied to countless major musicians throughout his career as a songwriter and collaborator - from producing Cliff Bennett, Paddy, Klaus And Gibson and the Bonzo Dog Doo-Dah Band, to appearances on sessions by Donovan, Paul Jones and Steve Miller. While Paul McCartney is regarded as one of the foremost musicians in the world, his live shows tend to garner more visibility and regard than may be demonstrated on the music charts. Paul plays Yamaha grand pianos on stage and in the studio."

Paul McCartney used this piano on his tour through North America. The instrument can be seen in his film "Rockshow" which was created during this tour. Video example: https://www.youtube.com/watch?v=Y0dxBnVSARM (6:22)
