Bob Dylan - Bob Dylan Drama Over Newport Folk Festival Guitar

Dylan's aides insist Dawn Peterson's find can't be one the folk rock legend left behind after his Newport show, where he first went electric, because the singer/songwriter still owns the axe - but experts working with U.S. show History Detectives beg to differ.

And they insist the guitar could fetch more than $1 million (Gbp625,000) at auction if Peterson decides to sell it.

She claims she had no idea the instrument her father, a private pilot for Dylan's manager Albert Grossman, found onboard his plane was perhaps Dylan's until the history experts alerted her to the fact she might have a treasure in her home.

Peterson tells Rolling Stone magazine, "(My father) saw there were three guitars left on the plane. He contacted the company a few times about picking the guitars up, but nobody ever got back to him."

But Dylan's lawyer, Orin Snyder, tells the publication there's no way the instrument can be his client's most famous guitar, even though it came in a case containing the singer/songwriter's scribbles and has been verified as the guitar the star strummed at Newport by History Detectives experts.

He says, "Bob has possession of the electric guitar he played at the Newport Folk Festival.

"He did own several other Stratocaster guitars that were stolen from him around that time, as were some handwritten lyrics."
