Dai Rhys

"As they say in Llandow, ciao for now"

-Dai, warning Terry away after he notices that Dai took a bribe.

Dai Rhys (also known as the Karaoke King) is a supporting character in Twin Town. He works for Bryn Cartwright, a powerful businessman in Swansea. In addition to his day job at Cartwright Roofing, Dai moonlights as a karaoke promoter. He is best friends with Chip Roberts, who helps him with the karaoke parties.

Prelude
Six months prior to events of Twin Town, Dai started an illicit relationship with Bonny Cartwright, the daughter of his boss. Due to her status as Bryn's daughter and the noticeable age-gap, the relationship was kept a secret by the couple. Despite this, Dai was able to see Bonny a regular basis as he was a family-friend who often visited the Pondarosa for late-night parties.

He has also known Terry Walsh for a number of years, as they have an uneasy relationship which could hardly be described as a friendship. If anything, they have a bitter rivalry which grows each time they see each other.

Biography
Dai is first seen when he picks up Fatty Lewis for the roofing job at the Rugby Club. While driving, Dai and Chip tell Fatty about their karaoke business and the upcoming West Wales Semi Finals. Fatty is not convinced, believing that karaoke is taking attention away from the traditional male voice choirs. They then pull up by Swansea Railway Station and nearly run Terry over, much to the amusement of the trio. An irate Terry criticises Dai's driving, but everyone else is laughing and making jokes. After a heated exchange, Dai inquires about the cocaine, which Terry and Greyo are about to acquire from Dodgy. Terry asks for the cash upfront and they arrange a meeting at the club later in the day. Before Dai, Chip and Fatty can leave, Terry reminds them to fasten their seatbelts. Ignoring his request, the trio laugh again and the van pulls away, leaving a frustrated Terry in their wake.

Later on, Dai, Chip and Fatty have begun work on the roof. Chip and Dai are on the roof itself, while Fatty is on a ladder. Fatty asks for a piece of wood, but Dai warns him that it is "dodgy as fuck." Teetering on the edge of the roof, Chip tries to give the piece, but he can't reach. Fatty then tries to grab the piece of wood, but his ladder begins to give way. Fatty cries out for Dai's help, but it is too late. While Dai is running across the roof, Fatty falls off the ladder and comes crashing down. He is later taken to hospital, leaving Dai and Chip continue to the job by themselves.

Dai is present when the twins drive an AC Cobra across the pitch. Smoking a cigarette on the roof, he watches in disbelief as the twins make a mess of the playing fields. Unaware of their father's accident, the twins call out to Dai and tell him that Fatty forgot his lunchbox. Chip tells them that Fatty has been sent to hospital after falling off the ladder.

By the evening, Dai and Chip have retired to the clubhouse for a pint. While playing a game of darts, Dai greets Terry and Greyo enthusiastically. When Dai's upcoming karaoke night is brought up in the conversation, Terry dismisses it, saying it is for people who want to "grab a granny." Dai turns the tables on Terry by remarking that Terry will "have no trouble."

hinting that the pair have known for each for long time.

Dai then makes an off-screen appearance when Bonny is seen talking on the phone. Unbeknownst to Bryn (and the audience), Bonny was talking to Dai, whom she was having phone-sex with.

Dai is last seen in the prison cell, dejected and feeling betrayed by Bonnie.

Epilogue.
After the deaths of Terry Walsh and Bryn Cartwright, it is likely that both Dai and Chip were freed from custody and cleared of all charges. Without the need for a scapegoat, there would have been no reason to keep them imprisoned. Greyo was still alive at the end of film and it is likely that he would have protested their innocence, as he knew the truth about the how the Lewis Family died.

Trivia
-Unlike Fatty Lewis, Dai is employed by Cartwright Roofing.It can be speculated that if Dai fell from the roof, Bryn would have to provide compensation, as Dai was directly employed by his company. According to Bryn Cartwright, Fatty was "working for himself" at the time of the accident, which meant that Bryn was not legally obliged to provide compensation. When a builder or tradesman does a side job (usually without telling their main employer), it is known as a "hobble." Because these side-hustles are often informal and "under the table", it can be harder to receive compensation if something goes wrong. This is what happened to Fatty in Twin Town, as Bryn was under no pressure to provide any financial assistance.
