Don Bosco had taught his choir members among the Oratory boys several hymns which he himself had composed in honor of the Child Jesus.
To make the atmosphere of Christmas felt, he decorated the small chapel as best as he could and even invited several hundred people.
After a few hours of sleep, he was back in the church, waiting for the larger crowd of boys that failed to attend the midnight Mass.
The Christmas season was celebrated this way for many years until Don Bosco had other priests to help him.
