Welcome and thanks for all your lovely messages. Much appreciated.
I know we're just into Spring but have you heard the song ' Summer Is Icumen In'? It carries on ' Loud Now Sing Cuckoo'. It's a medieavil English Canon or round where someone starts off singing and then another joins in but at the beginning of the song so that the words overlap and others also join in at regular intervals and it ends up with each singer finishing the song until the last to join in finishes.
It was discovered in a manuscript dated between 1261-65 owned by one of three monks of Reading Abbey, possibly William of Winchester and is sometimes referred to as the Reading Rota, this round is unique to this collection. The original manuscript is now held in the British Library but you can see it online here as it has been digitised. Have a look to see the full song plus translation.
The round has also been used in various films and TV programmes including Shadow lands.
Reading Abbey has so many famous connections!
