I'm not an opera fan, but have enormous respect for the talent and power of the real pros and have a couple Blu-rays in the collection to remind me once in a while. Here's one of my all-time favorite music videos: Paul Potts, the ordinary guy from Wales, a cellphone salesman, bringing down the house in his debut before an obviously-skeptical audience and table of judges.
This literally brought tears to my eyes the first few times I watched it, and still might. I think it's well-worth 4 minutes and 17 seconds of your time.
