Country star Martina McBride and Train singer Pat Monahan will debut their new duet 'A Song for You' on the upcoming PBS special, 'From Dust to Dreams: Opening Night at the Smith Center for the Performing Arts.' The show was filmed at the opening of the Smith Center in March and also features performances by an array of country and pop musicians.

"I am so honored to have been a part of the Smith Center's opening night," McBride says in a press release. "I am excited for viewers at home to see how magical the night was performing with some of the most iconic names in music." McBride and Monahan previously recorded together on 'Marry Me.'

Actor Neil Patrick Harris hosted the event, which also features Carole King and Jennifer Hudson collaborating on 'Natural Woman,' Willie Nelson and Merle Haggard performing their classic 'Poncho & Lefty,' and Nelson, Haggard and Emmylou Harris' rendition of 'Ramblin' Fever.'
