As the soundtrack - in many languanges - for a film about Don Bosco:
LyricsFather, for many people,
Father, just listen to our voice,
Which is the song of love
Your heart was always full of love,
Your spirit always young
What can you do for us?
Father, our guide and our friend
Young people of the world;
We still rely on you!
Open our hearts to Jesus Christ
Support our commitment in this community.
Ohhhh, ohhhh, ohhhh, ohhhhh.
Joyful, the life with you is joyful
The life with you is music;
A melody of love.
The love you have for all your children
Is still alive among us;
And this shall never die!
