“The famous drum break was an accident. We were playing, everything was good, and next thing you knew Aretha’s music came flying off the piano. Somebody had to come and pick it up, but while this was happening, she's singing: ‘Rock… steady… rock… steady.” And I did a drum break. It just came to me.

“We had that song down. The key to it was Chuck Rainey’s bassline, which was very fat. That’s the kind of bass that lets me keep the beat but turn things around. I followed Chuck, but he followed me, too. The funny thing is, I’m on top of the beat, not behind. I was anticipating Chuck.

“It’s one of the grooviest tracks ever, and it’s constant. When I played it, I didn’t think I was doing anything special, but when I heard it back, I liked it. It's funky. The tempo is there, the energy… Once you get a grip on that, you can’t lose.”
