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
