Goodnight Nurse was a New Zealand pop punk band and they has released two studio albums, "Always and Never" (2006) and "Keep Me On Your Side" (2008)
The song comes from the album "Always and Never" (2006) https://en.wikipedia.org/wiki/Always_and_Never
It's written on wikipedia that there are 14 songs in the album but one is missing it's the song "Simple"
This music exists because I heard about it on some forum and website like here : https://www.letras.com/goodnight-nurse/simple/
Look the comment on this one by "grace_e_f" on June 2008 : https://songmeanings.com/songs/view/3530822107858676877/
Or here the 5th comment of "LuCky_Se7eN" he talk about it : https://forums.soompi.com/topic/99-currently-listening-tocurrently-obsessedcurrent-favorite/page/702/
But this music is nowhere to be found :/ someone can help me ?
