NEW YORK, Nov 7 — No one knows better than Yoko Ono how far celebrity activism has come in the last 40 years.
With late husband John Lennon she sparked a generation of celebrity cause campaigning with their 1969 "Bed-In" honeymoon to demonstrate for world peace as the Vietnam War raged.
From Live Aid, Band Aid and even Farm Aid in the 1980s to Bono's tour of Africa with US Treasury Secretary Paul H. O'Neill earlier this decade, pop-star involvement in everything from politics to poverty reduction is ubiquitous.
