Tommy Torini at The Aces, located in the Tops casino, needs more performers to get a bigger audience. For each one you bring back, you get 3% of the cut (or 5% with a 50 Barter check) and fame within the Strip.
Recruit these characters one by one and return to Tommy Torini after each recruitment:
The Human Comedian: Billy Knight. He is found just outside The Tops casino by the gate leading to the Lucky 38. You can give Billy some confidence to haggle for his worth with Tommy (Requires a 25 Barter check), netting you 90 caps instead of 45. Alternately, using a 25 Barter check on Tommy Torini will get you 90 caps instead of 45. If you do both challenges, you will get 150 caps.
The Ghoul Comedian: Hadrian. He is found inside Atomic Wrangler Casino, and you must convince James Garrett to release him from his contract. He can be found on the first floor and upstairs aswell during certain times of the day; you will have to wait around for Hadrian to return to the stage at 2 PM to activate the speech to release him from his contract. You first have the option of a 50 Barter check or a 50 Speech check (allowing you to not pay any caps) when talking to James. If you select to pay him, you can try to pass a 35 Barter check to lower the caps to 100, instead of 150 caps. You could also convince him to lower the price to 75 caps if you have done favors for the Garrets. With the Terrifying Presence perk, you can intimidate him into letting Hadrian go for no cost. You can also just kill Garrett and then talk to Hadrian. Also, if you completed the quest Wang Dang Atomic Tango, the option to release him is there.
If any of the potential performers listed above are killed prior to starting the quest, the dialog option with Tommy Torini to help him recruit performers will not appear, and the quest cannot be started. The player can only select "Sounds great." after he tells you what entertainment the theater offers / tells you that he's running thin on acts. Swank will still refer you to the Aces theater if you ask him about earning some extra caps. A "Quest Failed:" Pop-up may or may not appear if a potential performer is killed prior to initiating the quest.
As each act is recruited, their name and talent appears on the marquee of the Tops sign outside of the casino. Because Billy Knight stands right in front of the sign, the player can observe that his name goes up immediately after he is given Torini's business card, before he even sets foot in The Tops. If one goes into the casino at the time stated, you can watch the acts. To hear them you have to turn your radio WAY up as it plays through a speaker and is not considered by the game as a character voice.
You can recruit all of the acts without returning for your payment or XP or fame each time. Simply note where the recruits are and do all four, then return to The Tops. Some users may have reported a loss of XP, cash or may have encountered bugs as listed below, but this was not encountered at all during the two play throughs that tested this. Same amount of fame, XP and cash were awarded both times, identical to what had been gained by doing each recruit separately.
Having a negative reputation at the Tops (e.g. Killing everyone after Ring-A-Ding-Ding) will prevent you from starting/completing the quest, because Tommy will be aggressive when you enter the Theatre.
