My oblique reference to the Grateful Dead spurred a flood of erudite emails from readers questioning the accuracy of linking the band with the song I fought the law but the law won. In fact the song has a very interesting history — see the excellent Wikepedia entry about it. It’s been recorded by numerous bands, including the Clash and Green Day. But my favourite rendition is the Grateful Dead’s, because they sing it as though they had indeed fought losing battles with law enforcement agencies, possibly in relation to narcotic substances. Apple cheekily used the Green Day version in their SuperBowl ad for iTunes.
