It is a great, great interview, real pleasure to watch - it is very civil, Keith doesn't play his usual "cool" media image, he is very calm, and focused. He also looks great, much better than the tired old man with moustache at the beginning of the 2007 tour.
Unfortunately it is very hard to understand because of the german translation, but I think that behind the german voice, Keith's speech would be very easy to understnad, unlike most of his interviews. Is he growing older? I mean in a good way. Maybe. It resembles more the style of Charlie. Way to go.
