• The Welsh rock band Funeral for a Friend's fifth studio album was named after this track. Explaining the album's title, vocalist Matt Davies-Kreye told CMU: "A friend of mine was mentioning how he felt that the best thing for the planet was for the human race to just drop dead and at times I can see and understand his way of thinking but a big part of me has this (probably) misguided faith in humanity to kind of steer the ship in the right direction for a change. So Welcome Home Armageddon is the idea of patiently waiting for the end to arrive at your doorstep and give you a nice big hug."
• Drummer Ryan Richards told Rock Sound magazine about this song: "Like 'Sixteen' this was one that Matt brought as an acoustic skeleton, it also changed a lot but kept the melody that attracted us all to the idea in the first place. As an album closer, it was always the clear choice - both for vibe and melodic content."
