One of the poems that Carol Ann Duffy read at Sunday's garden party was John Barleycorn. This poem was commissioned by the BBC's Culture Show for a pub-themed edition. It's a great example of how poetry takes on a different life when it's read out loud. It was quite moving to hear her declaim the litany of pub names. She enjoys the grape and the grain and said she didn't need to do much research to call to mind all the wonderful - real - names that feature in the poem!
