We are not familiar with Potter's religious beliefs (if she has any), but she's got the kind of breath control and copper-plated pipes that could win her a soloist spot in any gospel choir in America. Her comment that slow and swampy opener "Joey" was about "bad boys" made us wonder if she might be a preacher's kid. During the high-kicking (literally) funk-rock of "Only Love," that question quickly changed to how on Earth she got left out of the tribute to actual preacher's kid Aretha Franklin at last Sunday's Grammys.
