Charlie Worsham does "Cover Challenges" on his YouTube channel all the time, and his followers love it. He has 24 hours to arrange, record and mix it. He has done cover challenges for War's - 'Low Rider' and PSY's - 'Gangnam Style' just to name a couple.

His latest is Katy Perry's - 'ROAR', which he added some bluegrass to it. The video is funny too, so take a look at it and let us know what you think. It seems like Worsham might have a little too much time on his hands every now and again.
