This website has a page where people can upload videos of Dusty Springfield performances. There is some interesting material here, including commercials she made before she was a star. Take a look at the video of Dusty and Mireille Mathieu singing "The Look of Love". It's introduced by Burt himself, but it appears he's speaking French. I think the French is dubbed.
