Due to falling plaster (didn't see that in the weather report), the upper church at the Immaculate Conception is closed for Masses. Thus, Masses are down stairs, in what I like to call the Crypt Church, which is the term used at the Shrine of the Immaculate Conception, in Washington, DC (NE).
Because the "Lower Church" only holds about 400 people and more are expected for the 4 and 6 PM Christmas Eve Masses, those two Masses will be held in the Lowell Memorial Auditorium, courtsey of said Auditorium. However, the 10 PM Christmas Eve mass will be back in the "Lower Church".
If you are looking for beautiful music for your Christmas Eve Mass, then I recommend the Lowell Memorial Auditorium. Children's Choir at the 4 PM Mass and the enhanced Adult Choir at the 6 PM Mass.
That is all. (As the sound of the Bosun's pipe fades.)
