Sheryl Crow on 'Extreme Makeover' (VIDEO)

Singer Sheryl Crow appeared on 'Extreme Makeover: Home Edition' (Sun., 8PM ET on ABC). On the show, the singer helped Ty Pennington rebuild a home for Toen and Amy Starkweather. Ethan, the family's youngest son, is suffering from Prader-Willi syndrome. This is a rare disorder that can cause low muscle tone, speech difficulties and behavior problems.

Crow helped rebuild the family house, and then sang her song 'Everyday Is a Winding Road.' Ethan seemed to especially enjoy the music, and got up and began to dance, while mother Amy watched. Crow had this to say: "I grew up with my parents telling me there was nothing I couldn't do. ...I look at Amy and Ethan and I think -- here's a mom who's saying the exact same thing."
