Bono was moved by how Walesa couldn’t see his wife, Danuta, and kept thinking about how that must have affected them: he repeats the lyric “I will be with you again” with heady urgency throughout. He said: “A song like ‘New Year’s Day’ might be about war and struggle, but it is also about love.

It is about having the faith to break through and survive against all odds. Love is a very powerful thing. There’s nothing more radical than two people loving each other.” Lech and Danuta Walesa celebrated their 50th wedding anniversary in November. Bono and Alison celebrated their 37th anniversary a few months before. Bono was right about the power of love.
