Letterbomb has always been one of my favourites and I'm so happy they finally play it live more often. I remember Billie saying it's his favourite song on AI, so I always wondered why they rarely played it live. The "Where will all the martyrs go when the virus cures itself and where will we all go when it's too late" line is incredible and I got goosebumps every time I heard it live.
My daughter made a video for her younger sister on her birthday to that song. It was the way I heard it for the first time and was so cute, full of pics and vids of the two of them, it's become my association whenever I hear the song. ❤️
