"The second leg of the Diamond Dogs tour saw Bowie's musical director Michael Kamen drop out and a change of personnel that reflected the star of the show's growing interest in US soul - cue the considerable influence of Luther Vandross. The result is a more energised, funkier take on the set familiar from David Live.Bowie's performance veers between spirited and swashbuckling takes on the likes of Sweet Thing and Knock On Wood, and sounding on the verge of collapse on Big Brother, rather suggesting that he was relying on some artificial energy at the time.Still when it's good, it's very good and fans will need this.
