Cantabulous Nine
From Tardis Wiki, the free Doctor Who reference
Cantabulous Nine was the location of the Church of the High Exalted, which sat on a small island in the middle of the Petronic Ocean. It was there that the Concert of the Most Beautiful Music was held every ten years, renowned throughout the cosmos. One year, the Tenth Doctor and Donna Noble attended the concert.
