O. W. Owen. CF1 were the first choir from Wales to visit the province and performed to a pavilion of over 20,000 people. In 2017, the choir went for a week to Rhineland, Germany where they paid a musical tribute at the grave of Ellis Humphrey Evans – Hedd Wyn and participated in an afternoon service of worship at Cologne Cathedral.

CF1’s highlights include performing in the official opening of the Wales Millennium Centre in 2004; singing in the Millennium Stadium before rugby matches – and before the 2015 England Rugby World Cup; singing in the Basilica San Zeno Maggiore in Verona and Basilica St. Marl’s in Venice; performing Cantata Memoria - a multilingual text by Sir Karl Jenkins and Mererid Hopwood to mark 50 years since the Aberfan disaster with Sir Bryn Terfel, Elin Manahan Thomas, David Childs, Catrin Finch, Joo Yeon and Sinfonia Cymru, conducted by Sir Karl Jenkins at the Wales Millennium Centre; performing as part of the Festival of Voice – Cardiff’s first international arts festival.
