Oh I always thought mumbo jumbo meant a bunch of nonsense words as you stated. I will rethink it and call it magic. Magic's okay in my book. I wish somebody would mumbo jumbo away the covid virus and all of its side effects.

I always thought it was related to music: [Chuck] Brown didn’t just invent go-go, says Johnson, he reinvented what dance bands do. “It’s non-stop. We go from one song to the next to the next – there’s no break,” he says. That’s where the name go-go derives – it’s music with a beat that just goes and goes. Percussive solos are its signature – conga drums, cowbells, timbales, anything with a beat. These transitions between songs turn into crescendos that keep the dance floor buzzing. “That was Brown’s genius,” says Johnson. https://www.theguardian.com/us-news/2019/dec/14/washington-dc-go-go-music-hits-back-gentrification-sould-of-a-city
