I think he means that you might also try checking out some of the light opera/ artsong composers of the likes of Offenbach, who wrote Orpheus in the Underworld, which included the famous Can-Can tune.  They were quite partial to titles like "la fille de rose" and so on.  I've had a look round some search engines myself -always interested in French material- but the only references I could find led right back to Glenn Morgan's record.
