It was already a good night for 16-year-old Frankie Antonelli when he took the stage of his high school talent show to cheers from the audience. But his night was about to get a lot better -- Darius Rucker was planning to join the teen, who has Down syndrome, on stage.

Antonelli's friends and family can be heard cheering the teen on as he performs Rucker's hit 'We Still Got Time.' The cheers get louder at the 3:10 mark in the video above, when Rucker appears on stage with Antonelli and shows that even though he is a huge country star, he has managed to stay down to earth.

Rucker and Antonelli finished the song next to one another, with Rucker's arm around Antonelli's shoulders, and the duo ended the song with a hug on the stage of Wando High School in Rucker's native South Carolina.

Rucker is known for donating his time to helping young people on stage. He appeared at the 2011 ACM Awards performing 'Music From the Heart' with a group of developmentally disabled young adults. A video of that performance can be seen at Taste of Country.
