alongside the release of the album in November 1998 and is the most successful album's song. The single was accompanied by a music video which featured Katy alongside internationally known tenor, Konstantinos Paliatsaras and Spiros Labrou's children choir on a snow-filled mountain. Directed by Giorgos Gkavalos and his production company View Studio, the music video was filmed on the Hymettus in Athens, featuring artificial snow created by snow machines. "Mega Christmas Special" A television special dedicated to Christougenna Me Tin Katy produced and directed by Giorgos Gkavalos and View Studio, premiered on Mega Channel. The special features the music video for "Touli Gia Ton Christouli" and nine full-length video clips of Katy singing to the remaining songs from the album, except the song "Christougenna Xana". The video clips were filmed in various locations around Athens, including a busy street in Syntagma Square around the city's large Christmas tree and in a snow-covered field. The transition between songs was filled by a child giving a Christmas wish. While "Touli Gia Ton Christouli" is predominantly screened as a stand-alone clip on television music channels, the remaining clips are only screened as part of a complete television special.
