Listening to the song in a live, I'm struck by how the guitars remind me of Serge Gainsbourg's American funk sound, circa Love on the Beat and You're Under Arrest.
I seem to remember Christine in an interview saying how much she loved Gainsbourg's work from that era, describing it as 'very queer'. She's also performed Mon Légionnaire which although more associated with Piaf, was covered memorably on You're Under Arrest.
Experts will also notice one of the dancers rocking double denim, a style Gainsbarre immortalised on his Gainsbourg Live album from 1986.
Audiences in the UK can expect much more of Christine in the near future, with an appearance on Jools Holland in the next few days. I expect what we've seen so far will be just the start of a concerted effort to establish her as France's biggest export to the UK since the Norman conquest.
