Graduation

Today is graduation for a lot of students here (last day of the school year for a lot of kids) and they are playing the graduation march on loudspeakers in my neighborhood. Occasionally I will hear a name. I am assuming it is from the school a couple of blocks away but I cannot for the life of me figure out why it is being broadcast on the speakers. If you knew a graduate, wouldn't you be there?

(By the way, this loudspeaker with the church happens a lot. On special holidays they will play the mass happening at the church all day. Since Holy Week is almost upon us, I know what I will be waking up to next week)
