The Irish group, whose concert was scheduled to happen on over the weekend but was called off in the wake of the horrific attacks, paid their respects at a makeshift memorial made of flowers and candles, reported People magazine.
An Instagram post showed a white sheet with the band's autographs written on it in black ink. The sheet also contained messages of hope and despair like, "How can a man with so many friends feel so alone?" and "Love is bigger than anything in its way."
