Jimmy Page: How we wrote Stairway to Heaven

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.

Forty-three years after its release, the song continues to hold a place in many music fans' hearts.

Guitarist Jimmy Page gives a personal account of how a rock anthem came together.
