In 1973, Epic released a two-disc LP repackage of Spirit and Clear entitled "Spirit".
The guitar riff that occurs about :43 into "Taurus" is said to have influenced Led Zeppelin's Jimmy Page in 'composing' his famous intro to "Stairway to Heaven". Led Zeppelin opened for Spirit on an American tour in 1968, and also borrowed the riff of "Fresh Garbage" during early live performances of the song 'As Long as I Have You'.

^Guitar World Magazine, April 1997: "California's most enduring legacy may well be the fingerpicked acoustic theme of the song "Taurus," which Jimmy Page lifted virtually note for the introduction to "Stairway to Heaven."
