I had the indescribable pleasure of actually watching this play on broadway. I cannot tell you what it did to me. I believe this is one of the best songs ever written or performed. It gives me chills every time. Its okay if it doesn't effect you in the same way...there's something about musical theater that does weird things to my emotions.

That is the original version with Idina Menzel and Kristen Chenowith. Nobody can sing like Idina. But if you did enjoy that, there's so many clips and videos of the play on youtube...its easy to spend hours comparing different versions.
