Am I the only one that actually enjoyed Paul playing with the Nirvana boys? Cause like...I know the latest cool thing to hate is the Beatles, but it's kind of fucking silly to assume that it wouldn't work. It's not like the Beatles didn't play "proto-grunge" or anything. Ever. It also seems absurd to assume that Nirvana wasn't influenced by the Beatles in any way shape or form just like 99.9% of every subsequent rock band between the UK and US. Shit, they were being covered by their contemporaries.
I don't see him doing a disservice to Cobain in the least, in fact, if anyone would have the honor, if you call it, to front Nirvana in his place, it may as well be McCartney. Or Neil Young...but he did the Pearl Jam thing years ago.
...Shut up, ECH.
For the record, I like the Beatles, Nirvana and Foo Fighters. As horrid & hipster as this sounds, with regards to the Fab Four, I "prefer their early stuff"...lol....For me, they started to go off the boil from 1967 onwards. Of course, that doesn't mean that everything they did sucked after that, but the ratio of misses to hits (and I don't necessarily mean chart wise) started to shift in favor of the former.
While Paul does get maligned for his multifarious musical turkeys, there isn't a single member of the Beatles who didn't, at one time or another (in the band or solo) produce some godawful crap. So, no innocent parties there.
As for the performance itself, it was a bunch of guys having a jam which, more often than not, is more satisfying for the participants than it is for an audience. It was a bit of a song, not that well formed, thrashed around by some famous dudes who were clearly enjoying themselves. Given that Dave Grohl teamed up with J P Jones of Zeppelin for Them Crooked Vultures, I'm open to the possibility that perhaps Dave, Krist and Sir Paul could, potentially knock out some half decent tunes with enough rehearsal/studio time.
I didn't think this really reflected positively or negatively on any of their collective musical legacies. Some guys bashing out a riff for charity. Of course, the media could never just say that, they have to go for: 'Beatle fronts Nirvana!' OMGROFLBBQ!!111
