 In September 2008 , after his appearance on Britain 's Got Talent but before the release of his first album , Johnston embarked on a tour of Norway with the choir , performing at Stavanger Cathedral and <unk> Abbey , among other places . The tour was conceived because the Diocese of Stavanger is connected with the Diocese of Carlisle through the Partnership for World Mission . This was Johnston 's last tour with the choir . Johnston features as head chorister on one of the choir 's albums , The Choral Music of <unk> <unk> , released in November 2008 .
