ELS is correct. After Solemn Mass the Ite is chanted by the deacon. Though Mrs. Romulus and I were blessed to have a Solemn Mass for our nuptials, I confess I didn’t recall whether the Ite is sung in that form — so I’ve just dashed out to the car to check my copy of Fortescue. The answer is yes, it is chanted.
Okay, thanks for the correction.
