How strange - I woke up yesterday with the Munsters theme song in my head.

Well, pretty well every morning I wake up with obscure tunes playing in my head - a few months ago it was an obscure Canadian glam rock track from the 1970s which I heard one time on late night radio around that time (https://www.youtube.com/watch?v=di3rPBH4Ep0) so the overall idea isn't weird, but it's a strange coincidence.
