"The March of the Swivelheads" is actually a remix of the track "Rotating Heads" by "The Beat".
The film never had an official soundtrack released until 2016, thirty years after it came out because the director John Hughes didn't see the point. The only soundtrack item released at the time was a 2 track single.
If you search "Rotating Heads, The Beat" on YouTube there are a few results but I'm not sure which is the remix used in the film
