In Ronnie’s defense, it’s a bit harder to pogo around with a banjo, especially if it’s got a heavy resonator. That could explain her side-to-side tipping and swaying.
In school I was in a band, and our bass player was shouldered down with this old late-70’s Gibson bass that was indestructible, ugly, and heavy as a neutron star. And he was a little guy, too. During our gigs, our bass player had that same side-to-side tip-and-sway movement. I thought it was the goofiest thing, until I strapped on his bass and played it. When I tried to move around, because of the weight distribution, I found myself doing the same damn side-to-side tipping. I yelled at our bass player that he had to get a new instrument. He finally got a newer, lighter, and slimmer model, and it made a dramatic difference; he was suddenly able to move freely about the stage.
