Asked about his views on American politics, he said: "Well, you know right now America is in a state of upheaval. Poverty is demoralising. You can't expect people to have the virtue of purity when they are poor.
"But we've got this guy out there now who is redefining the nature of politics from the ground up...Barack Obama.
"He's redefining what a politician is, so we'll have to see how things play out. Am I hopeful? Yes, I'm hopeful that things might change. Some things are going to have to."
He added: “You should always take the best from the past, leave the worst back there and go forward into the future."
'The times they are a-changin'
"Come senators, congressmen, please heed the call. Don't stand in the doorway, don't block up the hall," and: "Come mothers and fathers throughout the land, and don't criticise what you can't understand. Your sons and your daughters are beyond your command. Your old road is rapidly agin'."
