Suzanne,
This is probably not the version you recall but I like it:

THE DROWSY SLEEPER
(as performed by Bob White at the Ark in the early seventies)

Awake, awake you drowsy sleeper
Awake, awake, it's almost day
Come and stick your head out at the window
And listen to what your true love says
Go then go then and ask your momma
If you my lovin bride might be
If she says no I'll court another
And never no more will bother thee
Awake, awake you drowsy sleeper
Awake awake it's almost day
Come and stick your head out at the window
And listen to what your true love say
I'd rather be in some dark hollow
Where the sun don't never shine
Than to see you with another
And to know you'll never be mine
Awake awake you drowsy sleeper
Awake awake its almost day
Come and stick your head out at the window
And listen to what your true love says
Oh can't you see those doves a flyin
Flyin in the pines so high
They are mourning for their true loves
Just as I do now for mine
Awake, awake you drowsy sleeper
Awake, awake it's almost day
Come and stick your head out at the window
And listen to what your true love says
Cheers, harpgirl
