Is the organ played for every Sunday service? Just holidays?

The organ is played mainly when the choir sings every Sunday

Sunday 9:30,11:30,5:30.

Organ and choir is played at 930 am Mass on Sunday. However there are concerts where guests come and play the organ as well. I believe you can find these on the churches website.

The main organ is played every Sunday at the 9:30am Mass

I think every sunday
