I have seen this claim more than once in this forum, and it doesn't sound right to me, so I am asking directly... Basically the claim is that if Weird Al Yankovich were sued over one of his parody songs, he wouldn't be able to use a fair use defense, because his songs mostly do not parody the original work.
The example given is his song Yoda, which is set to the tune of Lola by The Kinks. Yoda is about Star Wars, and doesn't even mention The Kinks, or Lola in the lyrics; so if parody is pointed criticism in joke form, then Yoda is not a parody of Lola, despite what tune it uses.
If Weird Al was sued by (Kinks songwriter) Ray Davies, it would be a simple intellectual property case over the tune; Weird Al only be able to use a fair use parody defense if he was sued by (Star Wars rights holder) Disney.
But wouldn't this require the courts to parse the content of a joke, to determine who/what the butt of the joke was?
The claim was made under a question about Acuff-Rose v Campbell, the famous 2 Live Crew case, inwhich a hip hop group released a song called Pretty Woman, which used the guitar riff and some of the lyrics from Roy Orbison's Oh, Pretty Woman. They were sued by the song's rights holder, but won, establishing that parody is grounds for fair use. In that case, even though Pretty Woman was clearly humorous in intent, the court did not comment on the humor, going so far as to use a definition of parody that, counterintuitively, did not mention humor. The court was clearly reluctant to comment on humor, probably because humor is subjective, and old white men were not the target of Pretty Woman's humor.
If we're splitting hairs between an original work that a parody is derived from, and the subject of the joke, you could similarly argue that Pretty Woman does not qualify as a parody of Oh, Pretty Woman, since the lyrics do not mention Roy Orbison or any of his songs. If that argument was made in court during the Acuff-Rose case, the plaintiff would've argued that referencing such a cleancut song and making it vulgar (as they did) was inherently parodic.
Weird Al famously always seeks the original artist's blessing for his parodies, so this scenario will probably never be tested, and any answer directly relating to Weird Al would be speculative. But is there any case law that supports this claim? Because the most famous and influential fair use parody claim would seem to directly contradict it. Acuff-Rose would seem to imply that the content/subject of a joke is immaterial to a fair use parody claim.
