Alex I thought the same thing in respect of the vocals, in fact on the track "Big Noise Transmission" I think he is miming, the vocals are exactly the same as the record and he is miles away from the microphone when he is "singing"!!
Not impressed with this rip off with the CD & Book package, the 2CD costs £10.99 therefore he is wanting people to stump up £45 for a 48 page booklet!
He never learns his lesson Numan and constantly wants to fleece hardcore fans, he is definitely doing himself no favours at all.
The other strange thing is how quickly he has turned around the DVD from the actual concert, he normal takes well in excess of a year doing the post production on his live DVD's this has taken barely 6 months, I hope it is a better quality DVD than his last few.
