Brandon Flowers' brother has been encouraging him to record 'Run For Cover' for years.
The Killers frontman first penned the track - which is about the story of a senator who mistreats his wife - in 2008 when the group were recording their third album 'Day & Age' but he wasn't satisfied with his efforts and set it aside.
He admitted: ''I was never happy with the second verse -- so we put it on the backburner.''
The group revisited the song after working on their 2013 greatest hits collection, 'Direct Hits', but still couldn't get it right.
Brandon recalled: ''We started to explore it and look at it again and I still got nothing.
''I could've done what I did on 'Mr. Brightside' -- and had the same lyrics on the second verse [as the first verse] -- but I was going to persevere with this one.''
And when recording latest LP 'Wonderful, Wonderful', Brandon's brother urged them to go back again as he sends him a demo of the song every year.
Brandon admitted: ''He likes to remind that this song exists and needs to be heard by the world.''
Australian musician Alex Cameron helped ''crack the code lyrically'' and suggested the second verse took the stance of the wife's perspective.
One surprising revelation about the song is that the late Bob Marley has a writing credit on it.
Brandon explained: ''I mention 'Redemption Song' in it, and his people wanted their money.
''I never thought I'd share a writing credit with Bob Marley, but I'll take it.''
One topic Brandon won't be writing about any time soon is food.
Speaking to The Guardian newspaper, he said: ''It feels that food doesn't really belong in rock'n'roll, somehow. The Cure had a song, 'Friday I'm in Love'. which goes, 'It's such a gorgeous sight, to see you eat in the middle of the night.'
''And there's 'Drops Of Jupiter' by the band Train which has the line, 'Can you imagine no love, pride or deep-fried chicken?' When I hear those songs I think, 'Oh no, dude.' ''
