I enjoyed this interview with Roger McGough in the Guardian.
This paragraph is typical:
McGough finds it demoralising when he goes on children's TV: "They say, 'Come on and read a poem,' and they're all very excited, but 'Keep it short, keep it short, it's for children.' OK. 'Keep it 30 seconds.' OK. Then you do your 30-second poem, and it's followed by someone coming on with a hedgehog for 20 minutes."
