Unfortunately you're going to have to put up with Jimmy Fallon growling his way through a Kenny Rogers impression to listen to Miley's take on Dolly.
Jimmy Fallon and Miley Cyrus recreated Kenny Rogers and Dolly Parton's 'Islands in the Stream' as part of Miley's continued presence on 'The Tonight Show' this week because you can't really have Miley around for a week and not make an homage to her very famous godmother.
That said, they could have just let Miley do 'Jolene' or something else by herself. There was no need for Fallon to get involved, unless there's a weekly quote of beard wigs that need to be used in NBC.
