The Wolf's song

A wolf prowls the night,
And fills it with a beautiful song,
It might fill you with fright,
But, it won't be long,

The song is a call,
For wolves around to know that he is not far,
And before the night falls,
And the last of the twinkling stars,

It will come to a stop,
The song will be along,
But, it will be heard everywhere nonstop,
For it is The Wolf's song
