The truly terrible BBC programme called the 'One Show' had a piece on Tolkien in Birmingham on Thursday the 10th April.

You can still watch it on the BBC IPlayer if you live in the UK and to spare you watching the dross it starts 5 minutes and 50 seconds into the program (5 minutes long)

The interview is Giles Brandwith and Robert Blackman who wrote 'The Roots of Tolkien's Middle Earth' about Sarehole Mill, then are two Victorian Water Towers in Birmingham the inspiration for 'The Two Towers' and finally Mosely Bog, is it the Old Forest.
