When Bob Dylan was about to perform at the Isle of Wight Festival in August 1969, English critic Michael Gray asked Grossman about the rumor that The Beatles might appear on-stage with Dylan. Grossman replied, sotto voce: "Of course the Beatles would like to join Bob Dylan on stage. I should like to fly to the moon." The contracts between Dylan and Grossman were officially dissolved on July 17, 1970, prompted by Dylan's earlier realization that Grossman had taken 50% of his song publishing rights in a hastily-signed contract.
