Don’t Stop Believin’ was part of “Rock of Ages” before “Glee,” but “Glee” was so massive I had to figure out a way to recreate it again. To do it totally different from “Glee.” That was … challenging. It’s a great version. I wanted it to feel more cinematic. The strings drove it more than the piano. We made it more of duet than even the “Glee” version. I’ve now put a clause in my contract where I can produce any song for you, except Don’t Stop Believin.’ I’m tapped out.
