Thanks to Chrissa for submitting this song lyrics

Jenny: How the universe began

What the future holds
Why do fools fall in love?
What happens to our souls?
Veronica: 'Cause true life's mysteries
Are what we hope to find
Always reaching for a reason
Searching for a sign
All (Jenny singing lead): To know the unknown (it doesn't mean that much to me)
To know the unknown (some secrets are just meant to be)
Don't want all the answers
'Cause one thing is true
As long as my heart beats
I'll always love you
So I don't need to know the unknown
Nikki: Is there life on other planets
What's the magic in a kiss
What dreams really mean
Who hears us when we wish?
All: Everybody's wondering (everybody)
Trying to understand (understand)
What all the revelations are
Castles in the sand
Chorus (Mandy singing lead)
Chorus (Nikki singing lead)
Jenny: You don't have to tell me
Just why you went away
Now that you've come back to me
There's nothing more to say
Nikki: All I really need to know
Is that you're here to stay
Chorus (Danay singing lead)
Chorus (Nikki singing lead)
Jenny: So I don't need to know the unknown
