Wow. I had no idea David Arnold could sing this well either. I actually like this version better than the original. I mean, Bassey's is great in its sultry and swaggering, polished James Bond ballad kind of way, but David Arnold sure packs a wallop of poignancy into the song with just his vocals and a piano. Thumbs up indeed.
He has performed several times at various Bond events, and I remember him singing Only Myself to Blame from World is not Enough on the Mayo/Kermode film review show once when they had him on to promote a Bond concert. Great voice I agree.
