One of the most legendary rock songs of all time, "Stairway to Heaven" by Led Zeppelin, might just be a copy-and-paste job. That's the claim of the heirs of Randy Craig Wolfe (aka Randy California), a legendary guitarist in his own right, a protege of Jimi Hendrix who formed the band Spirit when he was still a teenager and was a pioneer in the psychedelic rock category.
Spirit released the instrumental interlude "Taurus" two years before "Stairway to Heaven." Zeppelin toured with Spirit and often covered the latter band's songs when they opened for them.
Now Wolfe's estate, decades after the songs were released, is raising a copyright infringement claim over the issue.
