Did Rick Play on the Wall at All?????

This has bugged me for years. I've heard several different things. Rick played a few things, he didn't play at all. He just demoed

Does anyone actually know if he played on the Wall and on what songs?????

Any info would be greatly appriciated.

James Guthrie says "Rick played much more on the album than people give him credit for," including some Hammond organ, but doesn't specify which tracks are him.

Who is James Guthrie?

Their co-producer and sound engineer.

I've wondered if he composed the bits on the demo tapes and they were then recorded by someone else.

In the booklet for the "Is Anybody Out There?" Rick says most of his parts were recorded when he was sacked and he wanted to finish recording but wasn't allowed.

There's an unbiased account of what happened here.

Someone has very kindly put the complete performance credits for the album on the individual Wikipedia pages for each song. Normally I'd be skeptical about such claims, but they do have citations from Vernon Fitch and Richard Mahon's book "Comfortably Numb" (for which they interviewed David Gilmour specifically about this issue).

According to that, then, Richard plays synthesizers on "In the Flesh?", "Another Brick in the Wall (all parts)", "Goodbye Blue Sky", "Don't Leave Me Now", "Goodbye Cruel World", "Hey You", "Is There Anybody Out There?", "Nobody Home", "Vera" and "Run Like Hell"; Hammond organ on "The Thin Ice", "Another Brick in the Wall Part II", "Young Lust", "Don't Leave Me Now", "Hey You", "Comfortably Numb" and "Waiting for the Worms"; piano on "The Thin Ice", "Empty Spaces", "One of My Turns", "Don't Leave Me Now" and "The Trial"; and electric piano on "Young Lust" and "Hey You".

In fact, the only Wall songs on which Rick DOESN'T appear are "The Happiest Days of Our Lives", "Mother", "Bring the Boys Back Home", "In the Flesh" and "Outside the Wall". It turns out that he also played lots more piano than I had originally thought.
