The show will be performed at the Wales Millennium Centre’s Donald Gordon Theatre, the second largest stage in Europe, between 27 and 29 August 2026. Tickets for the performances are now on sale, on the Centre's website: www.wmc.org.uk/calon

This will be the theatre company’s biggest show since relaunching in 2022, during the Urdd’s centenary year, thanks to support from the Welsh Government.

A cast of over 100 young people, aged between 15 and 25 and from all over Wales, will perform in the musical with a live band. There will also be opportunities for young people to work on all elements of stage work, including technical, production and costumes. The young people will be mentored through the process of creating the show by professional artists and stage crew.

Calon will be jam-packed with the now legendary and extremely popular songs written by Caryl over 40 years, including the iconic anthem, Calon and some of Eden's songs. Caryl will be co-working on the musical with her cousin and singer Non Parry, along with two of her daughters, the movement director and choreographer Elan Isaac and actress, singer and presenter Miriam Isaac.

The youth theatre company will be promoting opportunities for young people to take part in the musical by travelling to schools across Wales from September 2025, and auditions will be held in in the new year.
