Question about dicography for Να χαρείς τα μάτια σου καλέ

Here:

http://www.stixoi.info/stixoi.php?in...s&song_id=7387

the song has a date of 1976.

But if you look in the comments underneath the lyrics, you see these notes:

Ερρίκου Θαλασσινού - "Ο Τυχεράκιας" (1968)
Ορέστη Λάσκου - "Ο Απίθανος" (1970)

What do these notes mean? Are they movies with the song? Or albums?

According to this -> http://www.musiccorner.gr/%CF%8C%CF%...1%CE%B5-68126/
song was created on the summer of 1968.

Both titles you mentioned, are movies.
Strange thing though is that, for both of these movies a unique movie-shooting of the song is being used.
