There is *this* which i suspect is NOT the one wanted:

THE LAMPLIGHTER'S SERENADE

As recorded by the Glenn Miller Orchestra on February 18th 1942 with Ray Eberle and the Modernaires.
Words by Paul Francis Webster, music by Hoagy Carmichael.


A moment after dark
Around the park
An old-fashioned gent comes parading
Dressed in funny clothes
But singing as he goes
The lamplighter's serenade

The old boy loves a talk
With couples on the walk
But when it's half after love time
He reaches for his sticks
And from his bag of tricks
He lights every star in the sky

And if a lady or a beau should answer „no"
He sprinkles their hearts with his magic
Then he steals away to sing another day
The lamplighter's serenade...

And if a lady or a beau
Should find the answer „no"
He sprinkles every heart with magic
Then he steals away to sing another day
The lamplighter's serenade...!
