You don't. They are MIMES : they never talk when they are performing.
If you show them the photo of the thief, they pantomime "music", which suggests you look in the All That Jazz cafe.
The two street performers Downtown are mimes, white-faced players who act out various activities without speaking.
On counterfeit island, if you start at your blimp, go right until you see the clown store. There will be two mimes, one on either side.
From the store with the two mimes in front of it. PICK A GREEN ONE!
Mimes are pantomime artists, who act out skits and routines without saying any words. There are two in front of Bobo's Clown Store in the Downtown area.
In front of Bobo's clown shop, there are two mimes. Show them the photo from the video and they will act out "making music". Go to the Jazz Cafe to look for the thief..
Finding him and catching him prove to be two separate problems. Get the timecard from the security guard (he's in the Clown Store) and print out the photo from the security videos at the museum. You can locate him if you ask the mimes at Downtown.
