I wouldn't exactly call 'Taurus' note-for-note with 'Stairway'- 'Taurus' to me seems more like an arpeggio study you would find in a student's music book. 'Stairway' is much more highly developed. I know Led Zep did 'steal' a great deal of their early music (none more so than 'Dazed and Confused') , but I think the accusations that Jimmy stole 'Taurus' are far from the truth.
