From the ‘Self Aid’ gig in 1986. For those of us too young to remember Self Aid, here’s the Wikipedia story:

“Self Aid was a benefit concert held in Dublin, Ireland on 17 May 1986. The purpose of the concert was to highlight the chronic unemployment problem in Ireland at the time, with nearly 250,000 people unemployed. The 14 hour concert was the largest that had ever been staged in Ireland.”
