There is quite a long tradition of Americans singing in French, which includes the likes of Eartha Kitt (posing here), Nat King Cole and Blossom Dearie. Then there’s also more recent numbers by April March, Nanette Workman and Dee Dee Bridgewater. Some of then sang phonetically, some of them fumbled along in French and others actually took lessons.
You guess it – all these artists can be heard on Radio Oh la la. I’m always looking for more, especially from the 50s and 60s, so if you have any tips, let me know.
