A wonderful rendition of one of my favourite classics.
The only thing I'd change would be to let the final orchestral hit take more time in fading out. Seriously, that's ALL I'd change.
I'm left a bit envious of your vocal abilities. When I was younger (about the time this tune was playing on the radio, in fact) I was working on building up the strength in my upper register and could, at the best of times, hit some of those high notes while standing on a ladder. But these days, not so much. I'm left flaying around and stretching for those high notes like a blindfolded kid swatting at a piñata.
