John Mayer and Norah Jones joined country's Keith Urban to pay tribute to one of the greats -- Dolly Parton -- with an acoustic performance of her 1974 hit, 'Jolene.'

The three Grammy-winning stars, who shine with different musical styles, came together to present the Song of the Year award to Lady Antebellum, but stopped to give a nod to Parton with a song.

Mayer and Urban donned acoustic guitars and all three contributed their vocals to the impromptu Parton dedication, which made special note of her recent induction to the Grammy Lifetime Achievement Award recipients.

Mayer's 'Daughters' took the Song of the Year award in 2005, and his 2009 album, 'Battle Studies,' took Best Engineered Album, Non-Classical earlier this evening.
