Série Gémeaux

On Disc'Az singles the SG prefix = Série Gémeaux. French Discodis distributed issues usually have AZ 10 ??? number and SG number. In such cases add the AZ number to label, then add Série Gémeaux and SG number to series.

SG or Série Gémeaux indicates singles issued with picture sleeves. Those also with AZ numbers can sometimes also be found in company sleeves. Singles without any SG number have only company sleeves or can be promos.
