Yes! I am Bobby Lopez, songwriter for Frozen, Avenue Q, and The Book of Mormon* and youngest winner of an EGOT-- Emmy, Grammy, Oscar and Tony Award.
(He was on Wait, Wait, Don’t Tell Me a couple weeks ago, because The Book of Mormon has been running on Broadway for so long, talking about the celebrations they have planned, and low their expectations were).
I fear this may have been a classic " you see what you expect to see", I don’t know why I first heard Bobby, maybe it was because the first I heard of him was an interview with Terri Gross, and it was with wife Kristin, talking about the songs from Frozen. But in my head he was Bobby Lopez, and when I did research, sure it also used Robert, but that didn’t really register.
It was harder than I expected to answer questions like performing arts? composer vs. songwriter?
