When Paul McCartney joined James Corden in the Carpool Karaoke car, the two took a trip to Liverpool and down memory lane. The two stopped for a selfie at Penny Lane, passed St. Barnabas church (where McCartney was in the church choir), and visited local shops and his childhood home. On the playlist during the segment: “Hey Jude,†“Let it Be,†“Drive My Car,†“Love Me Do,†plus a brand new McCartney song. Because Carpool Karaoke is never without its costumes, when Corden pulls out a few Beatles costumes, running them by the McCartney for advice, the singer isn’t amused: “The great thing about your looks is that anyone can pull them off,†Corden says. “Carry on driving,†McCartney replies. “Just stick to polo shirts and jeans.â€
