Thanks, tooter. It was just a fluke, actually. I hadn't even noticed the discrepency in the Getz album - probably because I was familiar with the DeJohnette tune.
Once you pointed it out, I went on a witch hunt through my records. As it turns out, the Compost album is right next to the Chick Corea albums that I was looking through. I haven't listened to it in years, but as soon as I saw it, something clicked in my mind, and I realized that's where that song came from.
BTW, interesting story from Dave about Vortex.
