This is something that is my style and sounds wonderful to the ears.
The name of the choir is St Phillips boys choir.

Libera, as we know it today, is the publicly performing boys section of St. Philip's Church choir from South London. Their concept is to make boychoir music more accessible to a wider audience, many of whom might be put off by the words 'church choir', by integrating classical and traditional music with a more contemporary, mainstream sound. The repertoire they sing as Libera is in addition to, not a replacement of, their church singing. It does not detract from the fact that the core activity of the choir is their duty as part of the Anglican parish church. When heard during Sunday services, they are more like other church choirs than the Libera we see on TV and hear on CDs.

To help distinguish between the two there have been different names given to their separate roles as a choral group - first, the St. Philip's Boys' Choir, then in 1990 they changed to Angel Voices, then to Libera in 1998 ("Libera" being the Latin word for "Free", the title of their 2004 album).

St. Philip's Church is over 100 years old and has a long choral history. Its choir was established many decades ago and became a firm foundation on which the future was built. As a result of this, the current key to Libera's public success and popularity lies with two former St. Philip's choirboys - Robert Prizeman, choirmaster, and Ian Tilley who is the sound and technical genius.
