Just managed to get my hands on an old Singing Together broadcast - it's the final request programme from Spring Term 1979 presented by John Amis. The musical delights include:-

Charlie is M'Darling
Sir Eglamore
The Marigold
The Shepherd and His Dog
Water Come a Me Eye
Auld John Bradleum
Chiapenecas

It's on an old reel to reel tape but the quality is excellent as my trusty Tandberg revealed.
