Alex,

Robin Williams sang "The En-Ron-Ron-Ron" on David Letterman a few nights ago, which may be the source of all the web versions. But the verses were different. Truly, if you had registered the copyright you might have a claim on some real dough. But on the other hand, I doubt if RW got it off Mudcat; more likely you both had the same great idea--you just had it first!
