Big - name collaborations

[crofty1984]

I was just listening to/watching I ain't no nice guy on YouTube. Lemmy meets Ozzy Osbourne. Oh that's interesting, two mountains of metal doing a duet... Hang on, where did Slash come from?
Love it.
Any others? I don't mean supergroups forming an releasing albums, just a couple of singles maybe.
