On Sunday night (July 9th), Stevie Nicks joined Tom Petty & The Heartbreakers on stage during their joint gig at London, England’s Hyde Park to revisit one of the first and best musical moments of the 1980’s. Nicks and Petty sparred off on their 1981 Top Three hit, “Stop Draggin’ My Heart Around.” The BBC reported that Nicks told the crowd afterwards, “You know that Tom Petty is my favorite rock star!”
