There are many night visiting songs and many songs with a ghost having to leave when the cock crows. The standard night visiting song, given in several postings above, has nothing in common with Child 248, the Grey Cock, other than a night visit and a cock crowing.

In the grey cock, the visitor is a ghost who kept a previously made appointment with the woman, and who, being a ghost, had to leave to leave at cockcrow. In The Night Visiting Song, the lover is alive and coming over to spend the night before going back to work in the morning.
