Since 1975, on the Saturday nearest to 17 May, Levellers' Day has been held in the Oxfordshire town of Burford. Levellers' Day commemorates the three Levellers, Private John Church, Corporal Perkins, and Cornet James who were executed there on 17 May 1649 following an army mutiny over pay and political demands.

THE DIGGERS’ SONG
by Gerrard Winstanley

You noble Diggers all, stand up now, stand up now,
You noble Diggers all, stand up now,
The waste land to maintain, seeing Cavaliers by name,
Your digging does maintain, and persons all defame,
Stand up now, stand up now. ,

Your houses they pull down, stand up now, stand up now, ,
Your houses they pull down, stand up now. ,
Your houses they pull down to fright your men in town, ,
But the gentry must come down, and the poor shall wear the crown. Stand up now, Diggers all.
