Lyric discussion by TheSoberPirate 

Minor correction, the correct lyric is probably "attack of a bluebeat" instead of "blues beat." Bluebeat was a term used to describe Jamaican music (early ska and R&B) in England. The term came from from a UK record label that released these types of music called Blue Beat Records.

It makes a lot more sense, given that The Clash sound is clearly more influenced by Jamaican music than straight up blues.
