But he was already a great performer and singer, so perhaps it's no surprise that his rendition of Garland's songs (and some of them are pretty great songs) comes off wonderfully. He has a strong voice that can belt as well as evoke tenderness, poignancy and romance. He can't dance and doesn't tell stories well, but it doesn't matter--the voice, the songs are all. He well earned his ovation at the end.
The disappointment is that on the disc I got from Netflix, there were no extras. I'd have loved to see some backstage footage, an interview, something.
