Bob Dylan dismissed Thursday a claim that a woman in New Jersey has the guitar he played at the Newport Folk Festival in 1965, when he was infamously booed for going electric.

A lawyer for the music icon said Dylan still has the Fender Stratocaster guitar which he played on July 25, 1965, prompting boos which forced him off stage after only three songs.

But a lawyer for Dylan claims the singer still has the Fender Stratocaster with the sunburst design that he used during one of the most memorable performances of his career.
