Live Aid was a baby Woodstock, a child of Woodstock, which I call Globalstock.

Woodstock was both a peaceful protest and a global celebration.

Woodstock happened in August 1969, long before the Internet and mobile phones made it possible to communicate instantly with anyone, anywhere. It was a time when we weren't able to witness world events or the horrors of war live on 24-hour news channels.

I opened the Woodstock Festival even though I was supposed to be fifth. I said, 'What am I doing here? No, no, not me, not first!' I had to go on stage because there was no one else to go on first - the concert was already two-and-a-half hours late.

Though it's frequently portrayed as this crazy, unbridled festival of rain-soaked, stoned hippies dancing in the mud, Woodstock was obviously much more than that - or we wouldn't still be talking about it in 2009. People of all ages and colors came together in the fields of Max Yasgur's farm.

I haven't seen my face since I started growing my beard, which was when I was a teenager, almost; I never shaved. So I don't really know what I look like.
