Stairway to Heaven was one of the biggest rock songs of the 1970s - loved, imitated and sometimes parodied. Guitarist Jimmy Page gives a personal account of how a rock anthem came together.
Some folks are born
made to wave the flag
Ooh, they're red white and blue
It ain't me, it ain't me
I ain't no senator's son
This Vietnam wartime song (1969) puts a spotlight on the unequal sacrifices hidden by patriotic spouting.
Rock group Buffalo Springfield (including Stephen Stills and Neil Young) perform their most influential song, For What It's Worth.
