Definition: 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.
Input: Passage: Bud Doyle is a jockey who has discovered the secret to get his favorite mount, Six-Shooter, to boost his performance. If he simply chants the phrase, "Whoop-te-doo", the horse responds with a burst of speed. There is a special bond between the jockey and his mount, but there is increasing tension between Doyle and the horse's owner, Pop Blake (who also raised Doyle), over Doyle's relationship with local singer Babe Ellis. Blake sees Ellis as a distraction prior to the upcoming big race, the Camden Stakes.
The owner of the club where Babe sings, Wally Weber, has his eyes on his horse winning the Camden Stakes. When the issues between Pop and Doyle come to a head, Pop tells Doyle that he has to choose: either he stops seeing Babe, or he'll be replaced as Six-Shooter's jockey in the big race. Angry and frustrated, Doyle quits. Weber approaches him to become the jockey for Rose Dawn, Weber's horse, and Doyle agrees, with the precondition that he not ride Royal Dawn in the Camden Stakes, for he wants Six-Shooter to still win the race.  Weber accedes to that one precondition, however, on the day of the race, he makes it clear that Doyle is under contract, and that he will ride Rose Dawn in the race.
Upset, Doyle has no choice but to ride Rose Dawn.  However, during the race, he manages to chant his signature "Whoop-te-doo" to Six-Shooter, causing his old mount to win the race. Furious that his horse lost, Weber goes to the judges, who rule that Doyle threw the race, pulling back on Rose Dawn, to allow Six-Shooter to win, and suspend Doyle from horse-racing.

What is the full name of the person who disapproves of Bud going to see Babe sing?
