U2 and B.B. King met in Dublin in 198. "Think of me sometime when you write a song", as B.B. King would say. This would be the start of a long lasting friendship between the band and the blues legend. In the slideshow we explore U2's friendship with B.B. King from the start until the very end, 14 May 2015, the day U2's new tour was born and the day when B.B. King sadly passed away.
