Ms Llynor said: "The intention of the show is to celebrate the contribution and legacy of Richard and Wyn Jones to the Welsh music scene. While the songs will be familiar to fans of Ail Symudiad, Ms Llynor said audiences can expect a new twist. She said: "They are all Ail Symudiad songs, there is no arguing about that, but Steffan Rhys Williams as music director has arranged them in the musical style of the 1960s rather than Rich and Wyn's period in the '80s. "John Lord claims that this will ensure the future of the town, with everything new and shiny. Cast members include Betsan Lees as Nansi, Llinor ap Gwynedd as her mother, Mefin Hughes as Morys, and Ryland Teifi as John Lord.
