Corden commented that in the play, Anderson had to face one of her deepest fears: singing in public. She explained, "I don’t sing. PJ Harvey wrote a song for me to sing that I had to sing every night, accompanied by a piano, and so I had to sing but I don’t sing."
Hanks revealed that his worst fear was accompanying his wife playing the guitar, despite only knowing the same "five and half chords" as Corden's band. Still, Hanks whipped out a guitar, and encouraged Anderson to overcome her fears one more time by playing The Beatles' "I Wanna Hold Your Hand."
We wish Tom Hanks would help us overcome our fears!
