I can only think of one other time Ritchie was smiling much at all and that was a brief second in a video when Deep Purple reunited in 1984. The video for Perfect Strangers to be exact. Love his guitar work even if he takes himself way too serious. And never realized just who all Martin Birch produced for. Sadly Ritchie pushed him out after the Dio years in exchange for Roger Glover who was not terrible, just not as legendary in producer circles is all. Great bassist in his day though.
