And of course, the only sure-fire way to knock a songworm out of your head is to replace it with another songworm. >:-)

With that in mind, I remind you of this Trav filk (http://lists.travellerrpg.com/pipermail/tml/2001-August/126788.html) I posted to the TML a while back. It may be an evil songworm in its own right, but at least it isn't your current affliction....
