Released as a single a day after the premier of Rocky III, the American rock band Survivor’s theme track hit number one on this day in 1982 on the UK charts. Written at the request of director and star Sylvester Stallone after Queen him permission for “Another Bites the Dust,” the demo version appears (though without tiger growls) in the film and the irregular time signature is meant to evoke throwing and landing punches. A success worldwide thanks in part due to extensive air-play on MTV, “Eye of the Tiger” won a grammy for vocalist Dave Bickler guitarist Frankie Sullivan and keyboard artist Jim Peterik. Used without authorisation as walk-on music for a number of Republican presidential campaigns, the band successfully sued to have the candidates—Newt Gingrich, Mitt Romney and Mike Huckabee—desist, although most lawsuits launched by artists are toothless as it is the host venue—sports stadiums, auditoriums—that have the licensing agreements with record companies to play music and both artists and hopefuls get to be obdurate about their politics.
