"once" isimli belgeselde dinleyebileceğiniz o güzel Glen Hansard şarkılarından biridir. filmde Glen Hansard bir sokak müzisyenini canlandırmaktadır ve yine aynı filmde "if you want me" şarkısı için birlikte düet yaptığı Irglová ise bir sokak satıcısını canlandırmaktadır...
Grammy Award 2008'de ve ocar 2008'de yine aynı filmdeki "Falling Slowly" şarkısı en iyi film müziği seçilmiştir.
Falling slowly şarkısının sözleri ise şöyledir;
I don't know you
But I want you ~
All the more for that
Words fall through me
And always fool me
And I can't react
And games that never amount
To more than they're meant
Will play themselves out
Take this sinking boat and point it home
We've still got time
Raise your hopeful voice you have a choice
You'll make it now
Falling slowly, eyes that know me
And I can't go back
Moods that take me and erase me
And I'm painted black
You have suffered enough
And warred with yourself
It's time that you won
Take this sinking boat and point it home
We've still got time
Raise your hopeful voice you had a choice
You've made it now
Falling slowly sing your melody
I'll sing along
