In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

OK. solve this:
Passage: The session, held the evening of July 5, proved entirely unfruitful until late in the night. As they were about to abort and go home, Presley took his guitar and launched into a 1946 blues number, Arthur Crudup's "That's All Right". Moore recalled, "All of a sudden, Elvis just started singing this song, jumping around and acting the fool, and then Bill picked up his bass, and he started acting the fool, too, and I started playing with them. Sam, I think, had the door to the control booth open ... he stuck his head out and said, 'What are you doing?' And we said, 'We don't know.' 'Well, back up,' he said, 'try to find a place to start, and do it again.'" Phillips quickly began taping; this was the sound he had been looking for. Three days later, popular Memphis DJ Dewey Phillips played "That's All Right" on his Red, Hot, and Blue show. Listeners began phoning in, eager to find out who the singer really was. The interest was such that Phillips played the record repeatedly during the remaining two hours of his show. Interviewing Presley on air, Phillips asked him what high school he attended in order to clarify his color for the many callers who had assumed that he was black. During the next few days, the trio recorded a bluegrass number, Bill Monroe's "Blue Moon of Kentucky", again in a distinctive style and employing a jury rigged echo effect that Sam Phillips dubbed "slapback". A single was pressed with "That's All Right" on the A side and "Blue Moon of Kentucky" on the reverse.
Answer:
What was the name of the show listeners began phoning in eager to find out who the singer really was?
