"The Importance of Being Idle" is a song on the British rock band Oasis' sixth album, Don't Believe the Truth, written and sung by lead guitarist Noel Gallagher. It was the second single released from the album in the UK, on August 22, 2005, where it debuted at #1. It was also the first time that Oasis earned two successive #1's in the same calendar year. It was written by Gallagher sometime during the summer of 2004, before the band made their final attempt at recording what would become Don't Believe the Truth. He got the title from the Mark Twain book of the same name which he found whilst cleaning out his garage (it belonged not to him but to girlfriend Sara McDonald.)
