A defunct boys' / men's choir (sometimes mixed, sometimes combined), active from 1916/17 until the 1970s or 1980s. Not to be mistaken with mixed choir [artist:33221d8d-d4a7-4505-af76-5e6f630c2711|Mechels Kathedraalkoor], which was founded in 1989 and can probably be more or less considered a follow-up to this choir.
