Legions of grunge aficionados rent their flannel shirts in despair at the news that Nirvana might be getting the Mamma Mia treatment.

News emerged last week – via the unlikely medium of a Britney Spears court trial – that Nirvana were to be commemorated in a Broadway musical based on the life of Kurt Cobain. Spears’ one-time manger Sam Lutfi is suing his former charge for breach of contract, and revealed during testimony that he and Cobain’s widow Courtney Love were “working on a possible motion picture or Broadway musical based on the Nirvana catalogue”. Lutfi subsequently claimed the project was, at present, only an “idea”.

Speaking to The Observer, Love has now categorically denied that any such project is in gestation. Love claimed that “There will be no musical. Sometimes it’s best just to leave things alone”.

Presumably frustrated with being relentlessly accused of selling Cobain’s legacy up the river, Love also used the interview to turn attention on some unlikely Cobain desecrators – the Muppets. Jim Henson’s foamy crew covered ‘Smells Like Teen Spirit’ last year, and Love wasn’t happy: “What the fuck’s with the Muppets? I happen to like Elmo and I think the Cookie Monster is interesting but I know him [Kurt] and I know he didn’t want to be a Muppet. It was a disgrace. Like pissing on a grave.”

Remember: it’s not too late to nab yourself that iconic bass from the ‘Smells Like Teen Spirit’ video
