Philadelphia barrister Francis Alexander Malofiy is suing Led Zeppelin for stealing the opening chords of “Stairway from Heaven” from Sprit’s 1968 song “Taurus.”

During a recent interview, Malofiy descriped Led Zeppelin as “the greatest cover band in all of history.”

According to report of Philly Mag, Francis Alexander Malofiy will show the jury that Page and Plant had ample opportunity to hear “Taurus” when Zep opened for Spirit on their first American tour in 1968, two years before they wrote and recorded “Stairway.”

Philly Mag continued:

“Malofiy doesn’t have to prove Led Zeppelin stole Spirit’s song; he just has to convince a jury that’s what happened. Assuming the trial goes forward — and that this time, he’s allowed to play recordings of both songs for the jury — there will be blood. “
