James Corden welcomes Lil Rel Howery to Stage 56 on what might be his only day off in the midst of an insane run of films, including “Free Guy.” And James asks Lil Rel how it’s been dating and keeping his faith during 18-months of Zoom existence. After, Lil Rel tells James about the role of stand-up in his life, from the first time he performed to his latest album, “Humbly Vulnerable: I Said What I Said.”
