Really enjoying this, but he's let down by his keyboard player who not only overplays, but managed to get the chords wrong for Life on Mars. Duff backing singers, too - but Earl Slick on guitar is great, as is the drummer (always the most important player in any band imo) Sterling Campbell.
I only watched a bit, but I can't imagine a player of Mike Garson's calibre making errors, more likely the chords were simply arranged differently from the ones Rick Wakeman played.
I've never really understood why David Bowie was rated as 'something special'. I've never seen him as 'being in the same league' (or anywhere near to it) as the likes of McCartney or Costello.
However I've watched his set tonight (and still not been that impressed) and thought that he was totally outclassed as a singer by the lady backing him on vocals (as well as on guitar) in 'Under Pressure'. I'd love to see a full set from her!
The "problem", such as there is, with Bowie's performance of Life on Mars in 2000 is that his voice has matured / mellowed / dropped / disintegrated (delete as appropriate) so much since the early 70s that he's had to lower the key from F to C, a whopping drop, so it just "sounds wrong".
