It could be claimed without doubt that our Cathedral Choir is one of the most professional Malayalam Christian Choir in the world. All credits rest with the dedication and devotion by the choir members and the efforts of Late Mrs. Mammen Mappilla nurturing the choir. To give the semblance of Angels singing in Heaven, a separate mezzanine floor is allotted for the church Choir inside the Cathedral. Our choir has won great laurels, releasing audio cassettes and CDs through their participation with eminent musicians from the music industry such as Mr. Jolly Abraham, Mr. H. M. Vareed, etc. As star attraction they regularly participate in various ecumenical events and have also performed in TV shows. After the demise of Mrs. Mammen Mappilla the choir is being efficiently mentored by Mrs. Jaya Mathew and Mr. George Joseph.
