Task: Question Answering
Input (English): Passage: In 1937 Mississippi during the Great Depression, three convicts, Ulysses Everett McGill, Pete Hogwallop, and Delmar O'Donnell, escape from a chain gang and set out to retrieve a supposed treasure Everett buried, before its locale is flooded to make a lake and provide electricity for the state. The three get a lift from a blind man driving a handcar on a railway. He tells them, among other prophecies, that they will find a fortune but not the one they seek. The trio make their way to the house of Wash, Pete's cousin. They sleep in the barn, but Wash reports them to Sheriff Cooley, who, along with his men, torches the barn. After Pete angrily blows up Cooley's police van, Wash's son helps them escape.
Pete and Delmar are baptized by a group of Christians at a river. The group then picks up Tommy Johnson, a young black man, who claims he has sold his soul to the devil in exchange for the ability to play the guitar. In need of money, the four stop at a radio broadcast tower where they record a song as The Soggy Bottom Boys. That night, the trio part ways with Tommy after their car is discovered by the police. Unbeknownst to them, the recording becomes a major hit.
The trio inadvertently fall in with bank robber George "Baby Face" Nelson, and help him with a heist, before he leaves them with his share of the loot. The next day, the group hears singing. They see three ladies washing clothes in a river and singing. The ladies drug them with corn liquor and they lose consciousness. Upon waking, Delmar finds Pete's clothes lying next to him, empty except for a toad. Delmar is convinced the ladies were Sirens and transformed Pete into the toad. Later, one-eyed Bible salesman Big Dan Teague invites them for a picnic lunch, then mugs them and kills the toad. 
Question: What are the full names of the people who help George "Baby Face" Nelson with a heist?
Output (English): Ulysses Everett McGill.
