Justine's Satisfaction singing?

Hey did anybody see Satisfaction on FX Tuesday? Well I was just wondering if that was really Justine singing? I think it sounds like her voice and if it is she's not bad at all.

I know that Michael J. Fox really sang in BTTF and he wasn't bad at all.

And of course I know Tina is now the lead singer of her own band. I haven't heard her yet but isn't weird then that all the Keaton kids can sing in real life?

On a another note, can we beg E! to do a true Hollywood Story on our favorite sitcom Family Ties. At least everybody is still alive and healthy. I know they did one on Beverly Hills 90210, Cheers, Three's Company and other classics why not FT??

Michael J. Fox did not sang in BTTF. He said it himself. If you watch "Light of Day" you'll really hear him singing.

I'm pretty sure it was Justine singing(not very well I might add). The guitar player in that movie was a way better singer. It's funny to look back and see Julia Roberts as the bass player.
