Since being announced as the lead of NBC’s Jesus Christ Superstar Live in Concert in December, John Legend has immersed himself in the role of Jesus.

“He comes prepared,” the rock opera’s musical producer Harvey Mason Jr., 49, tells PEOPLE. “He’s doing a lot of different things right now, but he’s focused completely on this show. He knows the show inside and out and I’m really impressed with how diligently he’s working on stage with the cast and the director. It’s a lot of hours, but he’s dedicated.”

Jesus Christ Superstar Live in Concert airs Easter Sunday, April 1 at 8 p.m. ET on NBC.
