It happens about 15 minutes and 30 seconds in. It’s happens after the flugelhorn introduction from the leader of the band, Chuck Mangione. It follows the entry of the full Rochester Philharmonic Orchestra and the spontaneous applause. Just about the time soprano sax player Gerry Niewood comes in. Right in there, kind of unexpectedly, there’s this short stutter in the recording. No, not in the recording, but in my pressed version of it.
“It’s a locked groove,” I once explained to my daughters, “an imperfection in the pressing of the vinyl disc.”
