Barbra:
Once I found the perfect love
And you showed me everything there was
To know of love
Time will not betray the truth
And for all the years we've shared
I celebrate with you
For you...

Josh: Un giorno t'incontrai
Barbra: And me
Josh: Pensai, "Adesso lei"
Barbra: Will be...
Josh: D'allora insieme noi...

Both:
Forever
You are all I know of love
How could I ask for more
You're everything I'm dreaming of
You're all I need from love
And every star above
Spells out your name
I swear I'll always feel the same
You're all I want

Barbra: From love
Josh: All I want from love
Dimmi
Barbra: (Humming)
Josh: Che per l'eternita
Barbra: Like a memory
Josh: Mi terrai ad abitare nei pensieri tuoi
Con te
Barbra: You are my only heart
Josh: In te
Barbra: I loved you from the start
Josh: Noi due
Barbra: Together not apart
