According to roadie Steve Parrish, Jerry Garcia played this Yamaha YC-45D organ on his first solo album, Garcia. The organ was up for auction by Sotheby's in 2021.

Chick Corea can be seen playing the Yamaha YC-45D Combo Organ with Return To Forever in the very first seconds of this video. Can be seen more clearly at 4:36.

This clip is from their 1976 performance on the Old Grey Whistle Test program on BBC.

In this photo, Miles Davis can be seen playing a Yamaha YC-45D organ on stage at Avery Fisher Hall in New York on July 1, 1975.

Seen in this YouTube video being played by Philip Glass. This was posted on Youtube in October 2020 and the video is from the the South Bank Show (S10, E12) which aired on January 18th, 1987. This means that this interview/music was initially taped in late '86 or early January '87. Skip to 17min, 38 seconds to view the dual-manual Yamaha YC-45D behemoth being played.

Another source has the Yamaha YC-45D being played on the PG's "Glass: Dance Pieces" album: http://philipglass.com/glassnotes/dance-notes-by-michael-riesman/

Michael Riesman (Philip Glass Ensemble's Music Director) notes "The three sections of "Dance" that were restored and are now being performed are Dance I, Dance IV, and Dance III. These are the only sections for which film was made. In the original production, Dance II and Dance V were performed without film. In recent years, Childs has presented the work with film sections only, with Dance IV replacing Dance II as a middle movement, and renamed "Dance II".

The restoration involved both image and sound. The image was transferred to digital along with the audio from the film. Since this audio was of relatively poor quality, due both to its optical format and to film deterioration, I was approached by the people involved in the restoration to find out if it could be improved. I went back to the original source materials and, using time-adjustment tools to synchronize with the film audio, replaced the entire audio track.

The album "Dance" was mixed from the same source tapes as the film track for Dances I and III. However, on the album, Dances II and IV were re-recorded. The re-recording of Dance IV was done without reference to the original and thus could not be synchronized with the film because the tempos are too different.

On the original recording for Dance IV the organ was a Yamaha YC45D dual manual electric organ, which was also used on the album for Dance II. On the album, pipe organ samples were used for Dance IV. As far as I know, no chords were changed in album version, but the use of samples, which are less aggressive than the electronic original, would have softened the dissonances."

In this video of Talking Heads live at The Old Grey Whistle Test in 1978, you can see Jerry using a Yamaha YC45D with a Yamaha CP80 underneath, you can see the YC45D at 0:54

Seen in this image pulled from a YouTube video, Terry Riley is clearly using a Yamaha YC-45D dual-manual organ. While Philip Glass also has used this model of combo organ for compositions (Glass: Dance Pieces and Einstein on the Beach mostly), it is Riley who had his Yamaha detuned with alternative tunings. This is possible because the YC-45D (and most "vintage" analog combo organs) have individual circuit boards per note and this could be accomplished by an electronics technician tweaking the voice coils / pots.

In the interview linked below, Mr. Riley states that his YC-45D was put into just-intonation and modified to output sound stereophonically:

"Around 1970, the Vox was replaced with a Yamaha YC-45D, 2-manual organ that my technical assistant, Chester Wood, modified to output stereophonically. He also added a tuning function that made playing in just intonation possible. Chet built one of the first digital delays fashioned out of an old 1950's computer we purchased from Don Buchla. This new digital delay dubbed "the shadow" made possible live performance in quadraphonic sound. The last phase of this organ performance period came in 1980, when I finally made the move to synthesizers and started using 2 Prophet V synthesizers stacked like a two manual organ in tandem with a polyphonic sequencer."

In the X account of Gentle Giant, Kerry Minnear's workplace is shown. It includes a Yamaha YC-45D on the left. This organ is also shown in the YouTube video "Gentle Giant - Live at BBC Sight & Sound 1978" (https://youtu.be/9z5IPrO9vjM?si=lq9dKsjl4UpoC257).

Seen while Micheal was a member of Tangerine Dream & is pictured in his Equipboard profile photo.

In the video in which Moonlight Matters is taking Future Music Magazine on a tour of his studio, at 1:06:46 he says "Next, this is the Yamaha YC-45D. It's actually an organ, a really basic organ".

In the YouTube video titled "Dixie Dregs - Punk Sandwich (Live 1979)" uploaded by Ajone Rousey, a Yamaha YC-45D can be seen in the background at 1:48 during T Lavitz's keyboard solo. This organ is also prominent on the live album "Radio Travel Tunes (Remastered) [Live At the Sigma Sound Studios, Philadelphia, PA, June 17Th 1979]," where it can be heard clearly in the left ear on "Country House Shuffle" at 0:30. Additionally, it can be heard faintly on "I'm Freaking Out" between 2:16 and 2:30, playing the lead line.

Mike Barson is playing a Yamaha YC45D; it can be seen quite clearly at 0:25.
