Whatever floats your boat...
Representatives of a 1960s band called Spirit has sued Led Zeppelin for plagiarism, claiming that "Stairway to Heaven" borrowed its melody from a Spirit song called "Taurus." "Taurus" was written in 1967, "Stairway" in 1972. A Los Angeles district court judge has just decided that the suit deserves a jury trial.
There's no way to deny that the arpeggio of the opening chords in the introduction of "Stairway" sounds amazingly like "Taurus." But the introduction to "Taurus" also sounds amazingly like the Beatles' "Michelle," if you ask me. So maybe the holders of the Lennon/McCartney songbook (aka the heirs of Michael Jackson) should sue the heirs of the deceased Spirit members.
But if the Spirit folks are going to sue anyone ever influenced by their band, I guess they should add Greg Lake to the list for "I Believe in Father Christmas," 1974. Because about 20 seconds into that song, I also hear "Taurus."
But wait. How could one song be "Stairway to Heaven," "Michelle," and "I Believe in Father Christmas" all at the same time?
