The lovely Cerys Matthews (first name pronounced "Care-iss"), formerly of the Welsh band Catatonia, is the person who yelled the bridge in "Cyclops Rock" on Mink Car. Cerys appeared on the album as a result of the advice of Mink Car producer Clive Langer, despite the fact that the line was originally supposed to be done by Joe Strummer of The Clash. From a September 2001 issue of Rockpile Magazine:
While in a London studio, TMBG intended to call upon punk rock legend Joe Strummer to chant on the coda of 'Cyclops Rock,' but instead chose Cerys Matthews of Catatonia. The Welsh bombshell flips out in a tune detailing the story of a fellow who feels betrayed by a woman.
"Joe was on the scene," Flansburgh adds. "But Clive suggested Cerys, who coincidentally happened to be working down the road. He'd just done a record with her. I didn't know Cerys from Adam. She's a total sport and has an incredible amount of character."
