Hello JP2008
By looking a little closer, it is possible that the numbers indicated on the mentioned scores could be found in the very big collections named "Un siècle de chansons Françaises", yellow books; there are several editions (1879-1919, 1919-1929, 1929-1939, 1939-1949, etc...)I don't have these collections.... one can buy them at Paul BeuscherGood dayVernonait
