I discovered this poignant song while downloading Grey's Anatomy soundtrack from Season 3 episodes. It was used in the ep "Some Kind of Miracle". This is the one where dead Denny re-appears in the show...
Unkle Bob is a band from UK and judging from their Myspace comments, they've become pretty famous when GA fans heard their song used in one of the episodes.
Swans Unkle Bob
By my side,
you'll never be.
By my side,
you'll never be.
Cos I'm fake at the seams,
I'm lost in my dreams.
I want you to know,
that I can't let you go.
And you're never coming home again,
And you're never coming home again.
By my side,
you'll never be.
By my side,
you'll never be.
I wanted to tell you I'd changed.
I wanted to tell you that things would be different this time.
But I see you, you see me,
Differently.
I see you, you see me,
Differently.
You tell me that you love me but you never want to see me again.
