There were a couple of bits of lovely music on Rivers Griff rhys jones last night 9/8/09. The first was a nice guitar piece and the second was an old classical choir song. Can anyone help me out? Phil
If the choral piece is the one I think you're referring to, it's Little Lamb, Who Made Thee, which is the words to WIlliam Blake's poem The Lamb set to music by Jon Taverner. Unfortunately I can't find any recordings to direct you to as yet.
If you're looking, bear in mind that several composers have also set this poem to music.
