Rockpalast (Rock Palace) is a German music TV show broadcasting on WDR. It began in 1974 and continues to this day. So many great bands have appeared on it and seeing that You Tube these days has a loads of the shows I thought I'd post a few links here to some of the best ones.
All the shows are full sets. Just click on the links.
Ian Hunter Band featuring Mick Ronson (not sure of the year).
