This is Norbert’s very first credited television appearance, from way back in 1977. Other appearances before this include McNamara’s Band and Stedman. Norbert went on to appear in an episode of The Agency, which was created and produced by Shaun Cassidy, who played one of the Hardy Boys.
Norbert plays Gurd, a member of a band. The Hardy Boys, as played by Shaun Cassidy and Parker Stevenson, are in Europe investigating the disappearance of their father who was there attempting to solve an art theft ring. They hook up with a musical trio in order to gain access to Dracula's Castle where a costume ball/rock concert is being held. Lorne Greene has the role of a Romanian Inspector, but he is really an art thief posing as Dracula. Composer and singer Paul Williams also appears as the headline act at the castle. I apologize for the poor quality of these screencaps.
