Jeff Marx (born September 10, 1970) is a composer and lyricist of musicals. He is best known for creating the Broadway musical Avenue Q with collaborator Robert Lopez. Together, they wrote all the show's 21 songs. Lopez and Marx both write lyrics and they both write music, together, in the same room, at the same time.
When asked if he’s at all familiar with the Bay Area, Marx says, rather humbly, “To be completely honest, I don’t know what bay you’re talking about.’” When he’s reminded just what the Bay Area is, he says: “I’ve only ever been out there sinigng with the University of Michigan Men’s Glee Club. That was like my fraternity in college, my social outlet. I was 19. I’m looking forward to seeing San Francisco as an adult. I can spend as much time as I want and see what I want. And now I’m comfortable being gay. It’s a whole different thing from when I was there before.”
