Serenade in blue Lyrics

When I hear that Serenade in blue
I'm somewhere in another world, alone with you
Sharing all the joys we used to know
Many moons agoOnce again your face comes back to me
Just like the theme of some forgotten melody
In the album of my memory
Serenade in blueIt seems like only yesterday
The small cafe, a crowded floor
And as we danced the night away
I hear you say forever more
And then the song became a sigh
Forever more became goodbye
'Cause you remained in my heart soTell me darling is there still a spark?
Or only lonely ashes of the flame we knew
Should I go on whistling in the dark?
Serenade in blue
