Kenny Rogers and Dolly Parton. Cher and Peter Cetera. Aaron Neville and Linda Ronstadt. Amy Grant and Peter Cetera (dude got around). Gwyneth Paltrow and Huey Lewis. And now : Carrie Todd's mom and her unidentified friend.
I'll let Carrie field this one: "Here is a pic of my mom performing in a talent show in 1973. She's the one in the giant [AWESOMELY AMAZING] bellbottoms, obviously. My grandmother makes a creepy cameo as the lady in green, sitting in the background."
