[Kraftwerk] David Bowie and something new?

I had a call from someone this evening who was at the Paris concerts. He said much the same as the posts that have already occurred in here. He talked about rumours that David Bowie was in attendance... I think someone else posted something earlier?... Does anyone know for a fact if he was at any of the concerts? He also mentioned that he spoke with Emil who said that a new release would happen soon. Keep Werking John www.keepwerking.co.uk
