Lyrics:

Nobody knows it but you've got a secret smile
And you use it only for me
Nobody knows it but you've got a secret smile
And you use it only for me

So use it and prove it
Remove this whirling of sadness
I'm losing, I'm bluesing
But you can save me from madness

Nobody knows it but you've got a secret smile
And you use it only for me
Nobody knows it but you've got a secret smile
And you use it only for me

So save me, I'm waiting
I'm needing, hear me pleading
And soothe me, improve me
I'm grieving, I'm barely believing now, now

[Bridge 1]
When you are flying around and around the world
And I'm lying a-lonely
I know there's something sacred and free reserved
And received by me only

Nobody knows it but you've got a secret smile
And you use it only for me
Nobody knows it but you've got a secret smile
And you use it only for me

So use it and prove it
Remove this whirling of sadness
I'm losing, I'm bluesing
But you can save me from madness
Now, Now

[Bridge 2]
When you are flying around and around the world
And I'm lying a-lonely
I know there's something sacred and free reserved
And received by me only

Nobody knows it but you've got a secret smile
And you use it only for me
Nobody knows it but you've got a secret smile

[Outro]
Nobody knows it, nobody knows it
Nobody knows it but you've got a secret
Nobody knows it, nobody knows it
Nobody knows it but you've got a secret
Nobody knows it, nobody knows it
Nobody knows it but you've got a secret
Nobody knows it, nobody knows it
Nobody knows it but you've got a secret
