Question: When Ray and Charlie are in the bathroom, they sing part of a song. What is the song they sing?
Answer: It's "I Saw Her Standing There," written by John Lennon and Paul McCartney, released November 1963. In addition to the Beatles, the song has been covered by Elton John, The Grateful Dead, Tiffany, and many others I'm sure.
In December 1963, Capitol Records released the song in the United States as the B-side on the label's first single by the Beatles, "I Want to Hold Your Hand."
Answer: When they were children, Ray witnessed Charlie being burned by hot bath water. I think Ray says something about how he was left to look after Charlie while Charlie was in the bath, and Charlie got burned by the hot water. That memory must be very strong for Ray, and not comprehending the passing of time, Ray did not want to see Charlie hurt again.
