The suit - brought by the estate of Spirit guitarist Randy California and members of the band - claims the acoustic introduction to "Stairway" was lifted from their 1968 instrumental, "Taurus."

The Wrap reports Led Zeppelin's response is light on detail, mostly denying the allegations or claiming insufficient knowledge to answer them. "Answering paragraph 11 of the First Amended Complaint, including the First Amended Complaint's footnote 1, Defendants admit that Led Zeppelin has been called one of the greatest bands in history and its members were and are exceptionally talented," the group's answer reads, "but otherwise deny each and every allegation contained in paragraph 11 of the First Amended Complaint."
