Sorry if this isn't strictly piano, but that old Hammond M3 had a nice set of keys that felt great, made a soft swishing sound that wasn't distracting and bottomed out, and popped back up, just right.
"A Story Left Untold" is an original composition that I recorded 1987-88 on a Tascam 246 Porta-Studio cassette recorder. The 1959 Hammond M3, 1980 Fender Stratocaster, Guild 301 bass were all played by me. The original rhythm track was from a Boss DR55; real drums over-dubbed at a later date. It's a testament to a modest home studio of that time period.
Jammin' on The Hammond
Fantastic! I love the Hammond, and have been making some feeble attempts at imitation on my Roland VR-730. If I strike it rich, I'll look into a vintage B3 someday! 
Enthusiastic but mediocre amateur.
TC3 Thanks, TC3. Glad you liked my blast from the past. The best thing about that old Hammond was the keyboards; great feel. As for that Hammond sound, Native Instruments B4 does a really great job, with lots of recognizable presets based on tunes from bands, Procol Harum, Santana, Traffic, Allman Bros. Sly Stone, and more; very configurable to use one, or even two, midi keyboards; plays as a stand alone or VST. A lot less money than a B3 and Leslie, and easier to carry.
If you're set on the real thing, an M3 gets pretty close to the B3 when you hook up a Leslie, even a little one like the 147. I bought mine in the mid 80s from a dealer for $500 with the bench, and included the addition of a line out, and delivery. They're out there, and I feel it's a buyer's market.
Rob Thanks, Rob. Glad you enjoyed it. The original recording was more than twice as long, the whole side of a cassette running at 3.5ips. So, I clipped out a big chunk using Sound Forge, which is why the ending is a little abrupt. Still, easier than trying to do that with tape. LOL.
Speaking of great recordings, Pat Matheny recorded the album "New Chautauqua" on a Tascam 246, playing all of the guitar and bass tracks. So, we're in good company.
