Just to add to this list (links to YouTube videos):
Patti Smith singing “You Light Up My Life” on Kids Are People Too.
Frank Zappa guest judging on Dance Fever.
Clearly he should. It just so happens that he’s collaborating with someone who I think is a talentless faker who’s trying to parley a limited and unearned fame into a music career. I am just stating my opinion on the collaboration itself so I don’t have to wait for the song.
Maybe Ashlee Simpson turned him into a zombie slave with a futuristic ray gun. I don’t care, I just don’t like it.
This is what I hold onto. Robert has always been a big fan of practical jokes. I haven’t read my Cure biographies in a while to cite exact stories but he used to screw around with the press a lot, say he had adopted 5 babies while on tour, those sorts of things. A lot of the singles they put out were not his favorite songs - he saved those for the B sides.
He was a fan of tongue in cheek type actions.
I’m just hoping that’s what he’s going for here.
He should write an autobiographical song about the experience: You Turned Me into a Zombie Slave with Your Futuristic Ray Gun (… And I Liked It). Ashlee can sing backup vocals on the chorus.
Now that I would like! 
Robert Smith related hijack:
Years ago I went to a Beat Farmers show. They handed out a pamphlet at the show. One page of the pamphlet was just a bunch of random sayings. One stuck with me forever (and I like the Cure).
It said: “the lead singer for the Cure is not a pussy. pussies are GOOD things”
Carry on.
One further thought for you guys - Smokey Robinson on “American Idol.” 
“If any of our songs ever did make it on the top ten, I’d disband the group immediately.” - Robert Smith
Pornography was a top ten album. That was in 1982. The Top, The Head on the Door, Kiss Me Kiss Me Kiss Me and Disintegration were all top ten albums. I’m really glad he’s not a guy to stick to his principles. I was a huge Cure fan for my entire adolescence. Of course I stopped listening after Disintegration, so there’s pretty much no way I would ever buy a single featuring Robert Smith and Ashlee Simpson.
Smith has a huge self-deprecating streak, and a healthy sense of humour. C’mon remember the video in the wardrobe falling over the cliff. Sometimes musicians (and perhaps British ones more often) don’t get so up themselves that they can’t muck around a bit.*
- I can’t explain the po-faced mediocrity of Radiohead or Coldplay in this context, so don’t ask
Lies, my dear.
