On Thursday, after a week’s worth of testimony and arguments, the jury came back with its verdict in a case that’s been decades in the making. At trial, Led Zeppelin members Jimmy Page and Robert Plant testified as well as Michael Skidmore, the Trustee of Spirit songwriter Randy Wolfe’s estate, who demanded in his lawsuit a rewriting of rock ‘n’ roll history. The jury also heard from a Spirit bandmember, musicologists and other witnesses and experts opining on such subjects as whether Led Zeppelin had heard “Taurus” before composing their popular song and whether the two songs were substantially similar.
