Kasabian - Last Friday (Black) Night

The gang went to the very salubrious surroundings of Dublin Castle for a gawk at Kasabian last Friday night. They were alright, good for a leap around although there were times when it could have been anyone up there. Anyway, they gave us a rendition of their fine glam single Shoot The Runner, which we were talking about in the pub before hand, actually the discussion went something like this;
Me:" I like that song Shoot The Runner, (singing) - Shoot the Runner, my Queen, Bitch! Da na na nur na na nur na na nur na nur Na! Na!"
The Coff:"That's Black Night by the Purple!"
Me:"Well, that's a good song too"
Is it just us or does it sound like they're about to launch into Deep Purple's Black Night in the middle of it?
