Today, there is also a modern boys choir in South London that sings chants, among other songs, as entertainment. They go on singing tours, appear on TV, and make recordings (they are signed under EMI). This musical group is known as Libera. The boys, ages 7 to 16, are trained in singing harmonies and often perform inspirational and religious music. There are about 40 boys, led by their Director Robert Prizeman. In addition to concerts, they sing regularly in church services along with a full choir at Saint Phillips parish, in London. Here is their version of Kyrie Eleison, a Gregorian chant:
eleison" and mean "Lord have mercy, Christ have mercy." The version by Libera used just the first phrase.
Here is one-- with a single singer-- that uses both, created by Antoine Daniel Mass, and available through
Corpus Christi Watershed.
So here is the same melody as above, but with the addition of a beat track; this was created by a YouTuber who calls himself "freshaintdead."
