In the 1990 Canadian children's movie "Tommy Tricker and the Stamp Traveler" there's a chase scene in a shopping mall. In the middle of the mall there is a stage and on that stage is a kid singing a song called "I'll Keep A-Running" and that kid is Rufus Wainwright, age 13 or so. I believe he also wrote the song.

This is a pretty obscure fact, although I did mention it in my 1996 book "VideoHound's Family Video Guide" (never updated and now sadly out of print).

If you go to a Rufus Wainwright concert, yell out for "I'll Keep A-Running" and see what happens. (I have no idea.)
