After telling his story to his empathetic fellow passengers, which include Billy Idol, he learns that Glenn and Julia are on the same flight. With the help of Billy and the flight crew, over the loudspeaker, he sings a song he has written called "Grow Old With You", dedicated to Julia. As Robbie enters the main cabin singing, Glenn tries to assault him only to be thwarted and shoved into a lavatory by the flight attendants with assistance from Billy and a large fan. Robbie and Julia admit their love for each other, and share a kiss. Billy, impressed by Robbie's song, offers to tell his record company executives about him.
