Looked like it was only during the first part. Looks like it might have been programmed in as a song by accident- the song title graphics (with no text) appeared at both the start and the end, with the annoying competition text popping up. No sign of these on part 2, thankfully.
Also, looks like it IS 2 episodes a week, which is really annoying. It means I'm going to miss numerous episodes. All three shown so far have neen from 1992- are we going to get any from other years?
