Joseph Parry's Te Deum: Premiere for lost composition

"The world premiere is taking place of a work by Welsh composer Joseph Parry written almost 150 years ago. Te Deum will be performed at London's St Giles Cripplegate church by the London Welsh Chorale (LWC) on Saturday. A text from the Book of Common Prayer, Te Deum was set to music by the young Parry in 1863 while in America."
