The song When You're In Love is performed by Perry Como .
When you're in love, when you're in love
There is no way on earth to hide it!
When you're in love, really in love
You simply let your heart decide it!
With every sigh, with every glance
With every heartbeat, you confide it!
You'll want the world to know it too,
When you're in love as I'm in love with you!
