Rare drafts of one of Dylan’s best known songs found in journalist’s archive could fetch up to $1 million as part of wider legacy sale

In March 1964, the rock journalist Al Aronowitz awoke to find Bob Dylan asleep on his sofa and the lyrics to Mr Tambourine Man crumpled up in his rubbish bin.

The 22-year-old Dylan had spent the night writing and rewriting his new song on a portable typewriter at Aronowitz’s home in Berkeley Heights, New Jersey, before chucking away the early drafts and stretching out on his friend’s couch.
