Normally I’m not one to be impressed by things but the way his voice changed impressed me. From what I saw, he had to think for a bit before thinking, his voice was at times a bit high, and a few other things that I can’t remember. All of that changed once he started singing though..... He was singing in the perfect tune, his words went in perfect order, he sang so smoothly.
The change he underwent was magnificent and I’d be interested in hearing any other songs he sings if he sings other songs.
