I've said it before, and I'll say it again- In Heaven I will be able to sing like Adele. ( Or Sarah McLachlan- I'm not picky).
On Earth, I have a friend that actually CAN. She doesn't sound like Adele, but she is insanely talented. As far as acting/singing, she is the most talented person I know. Check her out for your listening pleasure- Her name is Kandyce Marie Gabrielson.
