Slightly OT: St. Louis Cathedral

Okay, first of all, I haven't seen The Big Easy--although it is on my Netflix queue--but I have a New Orleans-related question, and this board seemed like a good place to get a quick, accurate response.

My dad's side of the family is from New Orleans, so I've been there a few times, but not in several years. My memory is therefore a bit fuzzy--does St. Louis Cathedral in Jackson Square have a bell tower that chimes on the hour? If so, does it also chime on the quarter-hour and half-hour? Does it just strike the hour, i.e., 12 chimes for noon, 1 chime for 1:00, etc., or does it preface each hour's chime with the Westminster Chime heard at the Clock Tower in London?

Below is a link to a midi file of the Westminster Chime:

Or does the Cathedral's bell tower chime something completely different?

Thanks so much for your help!
