I played the Narrator in a school production of 1066 & All That, the musical based on Sellar & Yeatman's famous book of 1930 [but previously pubd in parts in Punch] when I was teaching at Peckham Manor School, SE London in 1962. The Woad Ode is definitely NOT part of the original book of that musical, being much older; but it could of course have been interpolated into some productions, this being the sort of episodic show that invites such treatment. For ours, e.g., I wrote a few new songs/scenes about astronauts/cosmonauts & suchlike more contemporary "history", to bring it up to date.
