Stairway to Heaven was one of the biggest rock songs of the 1970s - loved, imitated and sometimes parodied. Now Led Zeppelin's classic track is back on the turntable, on a re-mastered version of the band's fourth album. 43 years after its release, the song continues to hold a place in many music fans' hearts.
