(Sorry about the clumsy title) I recently switched on the telly just as the credits of some film were on, and immediately realised that the song being played was a cover of T Rex's Solid Gold Easy Action, then almost as immediately that it was by The Fratellis. I didn't previously know this cover existed, I don't like the Fratellis and I wouldn't have thought I'd be able to recognise a song was by them as I only know that Chelsea Chelsea one and it doesn't sound anything like the SGEA cover, and they don't really have anything idiosyncratic or unique about them that makes them instantly identifiable either.
Does anyone cleverer than me about music and memory etc. know why this happens? Am I a secret lemonade Fratellis lover?
