I've never had a layover more than an hour an a half, as I recall, but even if I had all night, I don't think I could do what this guy did. And he did it flawlessly.  Recorded on his iPhone, you'll feel sorry for him as he belts out Celine Dion's "All By Myself" and the only ears to hear it belong to a ceramic turtle and the women's restroom sign.
