The Unthanks - Blackbird lyrics

I know why the blackbird sings A song so pure that comes from his heart He sings for his love who won't come back He sings because he is sad He sings because he is glad He sings because he is free Free to love somebody else Now he's abandoned me I know why the blackbird cries She cries for the love she'll never have The love that would take her far away So far she never comes back Come back, come back, come back Come back, come back, come back Come back, come back, come back Come back, come back, come back We are just a break in the waves We are just a feather in the storm Windward or taken by the tide To places we call home I know why the blackbird sings A song so pure that comes from his heart He sings for his love who won't come back He sings because he is sad
