Actor Tom Hiddleston is set star as Hank Williams, Sr. in the upcoming biopic, 'I Saw the Light.' So over the weekend, he crashed Michigan's 'Wheatland Music Festival' and sang some Hank. Pretty well, too!

I was surprised, after seeing pictures of Hiddleston, to realize that he's the actor who played 'Loki' in the 'Thor' and 'Avengers' movies. He looks much different with hair lighter than Loki's jet black. Loved the job he did in those movies and so I can't wait to see him in this one!

Check out this video, made by someone in the audience, of Hiddleston on stage at the music fest. I'm not sure he sounds a LOT like Hank Williams, but then again, who does? But it sounds great!
