Originally from the UK, Petula Clark is probably the most successful artist in both her native country as her adoptive country, France. Singers with cute French accents were all the rage, but even today, Petula remains the leader of the pack. Other English-language singers that come to mind are Jane Birkin, Blossom Dearie, April March and Nanette Workman (read my article about her at Filles Sourires).
Her style was also very prim and proper, which endeared her to an enormous audience. Her most well-known hit has to be “Downtown”, recorded in French as “Dans le temps”, which like many other hits can be heard on Radio Oh la la.
