He continued: "I traveled all over the world with Eric. He introduced me to Vaudeville and Jack Benny and welcomed me into his friend circle of impossibly talented writers and performers. He was my university. He helped me grow and find my voice. And he did all of it while finding himself. Eric never stopped becoming Eric."
