When Nick Saban and several Alabama football players were challenged to sing "A Whole New World" at a Dallas children's hospital, they gave quite the performance.

They followed up their karaoke session by challenging the next celebrity visitor - Los Angeles Dodgers pitcher Clayton Kershaw - to sing Alabama's fight song.

The entire Alabama football team visited Children's Health/Children's Medical Center Dallas last week, several days before defeating Michigan State in the Cotton Bowl.

Coach Nick Saban, Henry, quarterback Jake Coker, center Ryan Kelly and linebacker Reggie Ragland stopped at the in-house Seacrest Studios. The video sessions recorded there are broadcast throughout the hospital to the rooms of children too ill to visit the players in person.

Famous musicians, athletes and other stars take part in a Celebrity Challenge, in which visitors pose a challenge to the next celebrity.

The team's challenge came from Texas Rangers pitcher Derrick Holland. Coker then issued the next challenge to Kershaw, whose visit also took place last week.

Kershaw, a Dallas native, has done extensive charitable work, from making a personal donation to build a field for the MLB's urban youth academy in Texas to running his own "Christ-centered, others-focused" charitable organization called Kershaw's Challenge.

He's also, by most accounts, a pretty fun and good-humored guy who harbors a love for Taylor Swift songs and dressed as Little Bo Peep after the team clinched the division in 2008.

So it's not surprising that he rose to the occasion when he was challenged to sing about teaching the Bulldogs to behave, then giving a hearty Roll Tide. Watch the video above to see his rendition.'
