I think Allan Sherman is in that group, too, B&J, so the trio can do Hello Muddah Hello Faddah!
Macaulay Culkin and Nicole Kidman (before she became anorexic).
One of the Wilson sisters from Heart, and that strawberry blonde lady in "Unforgiven." The other Wilson sister, and Grace Slick, Linda Ronstadt, and maybe Wynonna Judd.
Well, then there's Sissy Spacek and Loretta Lynn, but we knew that.
Damn, it IS a music thread. (Better left here tho, I agree.)
