The charity concert, being held in London, was shown on a 40-metre screen in Custom House Square, Laganside.
Aid worker May Montague, who spent more than a year working in Sudan, was part of the crowd.
"I think it's great to see everybody here together, across the divides for other countries in far worse turmoil than we have experienced," she said.
The London concert, in Hyde Park, was one of 10 Live 8 gigs which took place on Saturday - one in each of the G8 nations, one in South Africa and a smaller gig in Cornwall.
The London gig was the biggest and opened with Sir Paul McCartney singing with U2 in front of an audience of up to 200,000.
The concert climaxed with Sir Paul leading a rendition of Beatles' classic Hey Jude.
More than 1,000 people of all ages watched the concert
On Friday, a series of events to highlight Northern Ireland's solidarity with the poorest nations of the world were staged.
A giant white band was stretched around one of the tallest buildings in Belfast - the Riverside BT Tower.
Another measuring 150 metres was wrapped around the Lanyon building at Queen's University.
Saturday's concerts have been timed to coincide with the G8 summit of world leaders in Scotland on 6 July and will call for more aid for Africa, debt cancellation and fairer trade.
A further concert will take place on 6 July in Edinburgh as the summit begins.
