The song Once And For All is performed by Barry Manilow .
You're a girl
After my own heart
You know your own mind
We are a similar kind
Separate yet intertwined
We speak with a single voice
But now we must make a choice
Whether to fall in love
Once and for all
Do you really want to have someone for good
Would you stay in love forever if you could
Do you want a friend who's always standing by
When your back's against the wall
Once and for all
We're a pair
Cut from the same cloth
Deep in our own soul
Alone and not perfectly whole
But seemingly in control
Afraid not knowing just where we are
But knowing we've come so far
So far that we just might make it
Once and for all
Search your heart and then
I want you to decide
Is simple love enough to keep you by my side
Can we stay together through the thick and thin
Through troubles big and small
Once and for all
Once and for all
Once and for all
Do you really want to have someone for good
Would you stay in love forever if you could
Do you want a friend who's always standing by
When your back's against the wall
Once and for all
Once and for all
Once and for all
