It was a male/female duet about 10 years ago, I watched on MCM. I don't remember who were singing on french. I remember that part of the man's name was 'Swan' or 'Swans'. They were a kind of relax dancing and singing. Woman had breathy feeble voice. Slow rhytmic music. It's close to 'Je t'aime... moi non plus' by Serge Gainsbourg & Jane Birkin but something from 90's-2000's.
