Exactly as i said. They know people like the comercial sound of the gypsy kings therefore they copy it and therfore they get paid. The area of paris is triangulated with st micheal at the top, st severin slap bang in the centre of the area and cluny La sorbonne at the bottom. If you look at a good map of paris then just out os St Michael stationis la Huchette and a tiny street called Harpe ( I think that was where the MOrrocan was!). The nearest bridge is actually Boulavard Du Pont Or Palais Au Change which runs from Chatelet straight across the island to the correct area of Paris. Do take a good walk around the whole lot It is a cultural hotpot of musicians and restaurants.
Good luck (I am jealous you are going I have no leave left.)
