A couple times over the last few months, I've done some research into what specific drawbar settings Rod Argent uses on his Hammond organ, but I haven't been able to find anything. I tried to match the original recording and used 8', 4', and 2' all at 8.
For the piano, I used a sample of a Steinway Model D. I don't know if that's accurate for this specific track, but in a few interviews in recent years, Rod Argent has mentioned that he bought a Steinway concert grand. In this article from Keyboard Magazine, he confirms that it's a Model D. Unless I can find specific information about what brand of piano was used on a particular track, I'm probably going to use this sample as a default.
