there's a live version that i used to have an mp3 of but i can't find it. it has one of Andy's most passionate renditions of this tune. he just absolutely nails a sweet solo live!
I'm pretty sure everyone's already commented on the 'eleven' thing, but as for how the track's title came about... Well, why WOULD an English guy be thinking about the Kiswahili for 'eleven'? What turned his thoughts that way?
