A musical about a Derry nun whose cause for sainthood is being considered by the Catholic Church has been performed in her home city for the first time. The production, titled A Famous Nun: Clare Crockett - A Life Brought to the Stage, opened at St Columb's Hall in Londonderry on Friday. A second performance is scheduled for Saturday, which would have been Sister Clare's 44th birthday.

Sister Clare Crockett died in April 2016 when an earthquake caused the collapse of a school in Ecuador where she was teaching music. Born in Derry in 1982, she grew up in the Brandywell area of the city. As a teenager she aspired to be an actress. During a trip to Priego in central Spain in 2000, she attended a Catholic pilgrimage and later said she felt called by God. She joined the Servant Sisters of the Home of the Mother at the age of 18 and subsequently worked with young people in Spain, the United States and Ecuador.

The musical was written and composed by members of her religious order and was first performed last summer at a Marian Eucharistic event in Spain. The Derry performances are the first time the production has been staged in English. It features a cast of women aged between 15 and 21 from across the island of Ireland. Following the Derry shows, the musical will be performed in the US.

Speaking to BBC Radio Foyle, Sister Clare's sister Shauna Gill said the production was being performed with great affection and that the cast were eager to learn about her sister's life. She said her sister had at times wanted to be rich and famous but also wanted to be a nun, and would joke that she could become a famous nun.

Sister Rachel Maria, who helped bring the production to Derry, said the musical examines Sister Clare's life before she became a nun, including how she encountered God and how she struggled to respond to her vocation. She described Sister Clare as special and talented, recalling her humour and the joy she brought to those around her. Sister Rachel said the production was brought to Ireland as this year marks the tenth anniversary of Sister Clare's death.

In 2025, the Catholic Church declared Sister Clare a Servant of God, the first formal stage in the process that can lead to sainthood.
