Forty years ago this Sunday, the BBC radio's epic 1981 dramatisation of The Lord of the Rings reached its half-way point with Episode 13, 'The King of the Golden Hall', in which Gandalf, Aragon, Legolas and Gimli arrive at Meduseld and present themselves before King Théoden of the Mark.
Elsewhere in Middle-earth, Frodo, Sam and Gollum struggle on towards Mordor, traversing the dread-filled Dead Marshes, depicted here in Eric Fraser's original art for the accompanying programme-billing in Radio Times.
