@schuth I thought I should report back on some subsequent research. I have since listened to The Witch Doctor, which came out two years earlier, in 1961. I’ve had it in my collection for a long time, but I’m honestly not sure I’d ever listened to it with headphones before. Well. Every track is mixed the same way as Bu’s Delight: piano & bass centered, and everything else panned hard right or left. Gotta love the early 60s, when stereo was still a novelty and there were almost no rules or expectations.
