From Quiz "Sunset Boulevard" Tunes
Answer:
"Sunset Boulevard"
Norma finds out about Betty and calls her up, saying, "You do know a Mr. Gillis? Well, exactly how much do you know about him?" Joe finds her doing this, grabs the phone, and tells Betty to come over to the house and ask him herself. She does, and he admits that he's liked the comforts that money can give him. Betty leaves the house in tears since she can't persuade him to come with her. Norma thanks Joe tearfully, but he silently goes up to his room, packs his things, and starts to leave. Norma tries to persuade him not to, saying she needs him desperately, but he only tells her the truth - that her fans have forgotten about her and Hollywood is never going to produce her horrible script. Norma calmly picks up a gun and shoots him on his way out.
