Show with Jimmy Fallon performing her single Stolen Car.
It was, surprisingly perhaps, Farmer's US TV debut. Sting is unquestionably a bigger name in the US that Farmer is, and his presence may have helped persuade the show to put her on.
The song was, of course originally by Sting, appearing on his 2003 Sacred Love album.
Farmer's version reached number one in France on its release at the end of August, and features on her Interstellaires album.
Before they performed their duet, the pair appeared for a brief good humoured interview with Fallon.
There's been more of a focus on establishing Farmer as an artist in the USA with the release of Interstellaires, with an interview appearing in Rolling Stone magazine in September.
An CD EP featuring five remixes of the track emerged at the end of last week, two vinyl releases of remixes are expected at the end of January.
