WKBD had Son of Svengoolie as part of its double-featured Chiller Movie, which aired at 11PM (10CT.) Sven aired first, weaved-in with the feature being shown, then the second feature without. Also, this block had two intros: the main one which can be seen at www.youtube.com/watch?v=0m_mwYwXB4Q, followed by the "big broadcast" as seen above.
For local flavor, there were voice overs of Sven doing "return-to-feature" announcements for his segment of the Chiller Movie. On one Saturday night, I remember him making reference to the legendary Bill Kennedy, who at the time was WKBD's midday afternoon movie host as a quick gag.
WKBD stopped airing SoS after Field sold the station to Cox in 1984.
