Oh totally ludicrous. As ludicrous as Joe Strummer, the son of a Second Secretary of the Foreign Service, posing as a street boy growing up under the shadow of The Westway - I make everyone in that band equally as pretentious.
Or Keef Richards and Shane McGowan having both been Westminster Choirboys. Everyone's at it b. Daniel Day Lewis has started reminiscing about his days on the Millwall terraces for fúck's sake - the son a poet Laureate!
