Could Led Zeppelin have stolen the intro for the now-standard “Stairway to Heaven?” A lawyer representing deceased Spirit guitarist Randy California is making the claim and seeking to prevent the release of their reissue “Led Zeppelin IV” album according to Bloomberg Business.

“Stairway to Heaven” was recorded in 1971 and the claim from lawyer Francis Alexander Molofiy is that it was stolen from his client’s 1968 song “Taurus”.

“The idea behind this is to make sure that Randy California is given a writing credit on ‘Stairway to Heaven,'” Malofiy said. “It’s been a long time coming.”

Today.com reports that Led Zeppelin and Spirit, who had a hit with “I Got a Line on You,” played four gigs together in 1968 and 1969, shows at which Businessweek claims Spirit played “Taurus.” It also alleges that Led Zeppelin played a medley of songs that included Spirit’s “Fresh-Garbage” — a song that appeared on the same LP side as “Taurus” — on their first U.S. tour.

In an interview with Listener magazine published the year of his death, California said he felt “Stairway to Heaven” was a “rip-off.” “The guys made millions of bucks on it and never said ‘Thank you,’ never said, ‘Can we pay you some money for it?'” he said. “It’s kind of a sore point with me. Maybe someday their conscience will make them do something about it.”

Spirit and California’s family have waited until now to challenge the song’s authorship because they did not have the means to pay attorneys. At the end of California’s life, he would play sitar at an Indian restaurant in exchange for food.

A rep for Led Zeppelin declined to comment for Businessweek’s story, but Page discussed the band’s history with crediting songwriters after the fact in a recent interview with The New York Times. When asked why the group waited to credit Willie Dixon for bits of lyrics and melody that made their way into “Whole Lotta Love,” he acknowledged, “Within the lyrics of it, there’s (Dixons’) ‘You Need Love,’ and there are similarities within the lyrics. Now I’m not pointing a finger at anybody, but I’m just saying that’s what happened, and Willie Dixon got credit. Fair enough.”
