This has bugged me for a long time, and I think I might have finally figured it out. In 28 Weeks Later, you know the scene near the beginning, where the US-led military coalition is repopulating London? The kids in the movie arrive on a train, with a lot of other people. If you listen carefully to the background music, you might be like "hmmm, this sounds familiar, haven't I heard this somewhere before??" I think they might have drawn some of the instruments, some of the beat... (I don't know how to express this musicologically, but just some of the music, OK) from the Supertramp song School. The only video I can find of that scene has very muted music, so you might not even be able to hear it, but see if you can hear what I'm trying to describe. It would sort of make sense, actually, because the kids are arriving for their first day in the little colony, and the rules are being laid out for them, like the first day of school. Of course, the kids don't pay any attention to the rules, which eventually results in the entire world being overrun by the Rage virus. Oh well.
Here is the Supertramp song, School. Listen especially to the instrumental part from about 2:13 to 3:17.
