Bohemia Goes to Earth "Magnum" - Paris has built a Maginot line of pleasure, with nightclubs and cafes deep down in cellars. At the Club Saint Germain des Pres the musicians are very informal but their jazz is good. Drummer, Pianist and Clarinettist are kept busy most of the night. Their sleeves may be turned up for the musical fray, but their swing is surprisingly good, and the tunes they play blend with the mood of the club's customers.
