Colin Hay how long will it last

I knew this piece of string
Ties us together
But will it ever break in two
I don't believe what they say is true
That nothing lives forever
But I keep asking you
How long will it last
Now the dye is cast
Does this love have to fade away
How long will it last
When you walk into the room
My whole world gets brighter
And with a smile you wash my fears away
But that old familiar tune
Walks in behind her
And then she sings to you
How long will it last
Now the spell is cast
Does this love have to fade away
How long will it last
I used to think that nothing really matters
I could turn my head and walk away
There's no crystal ball
Long ago it shattered
Leaving only echo's in the hall
Here we are again
Another day is over
An so we kiss the sun goodnight
And all we really know
Is what we believe in
We may be wrong, we may be right
How long will it last
Will the feeling pass
Does this love have to fade away
How long will it last
Does this love have to fade away
How long will it last
