Bob Dylan "knew what he was doing" from the very start of his career, according to the man who played a key role in the singer's musical education.
Israel "Izzy" Young was running the Folklore Center in Greenwich Village in the early 1960s when a young Jewish musician called Robert Zimmerman walked in. The two, who are still in touch today, became good friends, with Mr Young later organising Dylan's first concert in Manhattan and Dylan writing a song about the centre.
Fifty years later Mr Young is selling a rare piece of music memorabilia - the typewritten lyrics of a Dylan anti-nuclear song that was never released.
Go Away you Bomb, which is being auctioned by Christie's in London next month and is expected to fetch up to £35,000, was written in 1963 while Dylan was working on his second album. "Why didn't it come out? I've never found out - I've only asked him about 50 times," said Mr Young.
