Only just realised that the female backing vocalist on Marilyn Manson's "Long Hard Road Out of Hell" was none other than Kelli Ali of the Sneaker Pimps. In fact the song was a collaboration between the two bands, though they didn't really hit it off, in spite of Manson praising her vocal.
Also and I know I've mentioned this before, only realised quite recently that Neon Lights, the B-Side of Vertigo, was a Kraftwerk cover. For some reason assumed it was a U2 track.
