Cover art for I Don't Know lyrics by Big Audio Dynamite II

This song is about and sung to Joe Strummer. It's Mick Jones reflecting back on his time with The Clash. At the start of the 3rd verse (just as the vocal gets the heavy FX) the "Ooh" is clearly replaced by "Joe". "You think you can run" is a reference to Joe Strummers running marathon's + disapearances (as well as a metaphor for him trying to escape from various issues). It's an angry song but it's also full of regret "There's only one regret I can't get through to you".
