Some of her content definitely was pushing the boundaries of what was allowed in country music radio in the late 1960s.
She can’t match the power of Reba’s voice in her version of “Fancy” but I find Bobby’s softness gives her rendition an element of vulnerability. It’s the same quality that makes her character in “Louisiana Man” (one of my favorites of hers) seem child-like and takes you back to the time in your own childhood when the world seemed impossibly big and even the simplest things seemed special.
She pulled a Howard Hughes and walked away from music while she still was relatively popular and became a hermit. The tabloids say she’s only been seen in public once in the 40+ years since she retired, but I expect that’s an oversimplification. It’s not that she hasn’t been seen, it’s just that she keeps a low profile and doesn’t get recognized.
