Accompanied by a claque of male musicians dressed in frontier chic, Miley performed in a high-waisted pair of black and white pinstripe slacks.

Her artfully rumpled white shirt was tucked in, and the 25-year-old left several buttons undone to reveal her tangle of necklaces.

Sweeping her blonde hair partly back and letting the rest of it fall forward to frame her face, the daughter of Billy Ray Cyrus rounded off the look with a pageboy cap.

George and his co-stars John Turturro and Tim Blake Nelson did not, however, sing themselves – the vocal was filled in by Dan Tyminski, Harley Allen and Pat Enwright.

Dan, Harley and Pat’s stirring rendition of the now century-old song went on to win the Grammy Award for Best Country Collaboration With Vocals.

Miley, who is engaged to Liam Hemsworth, has never won a Grammy, though her 2013 record Bangerz was nominated for Best Pop Vocal Album.
