When I was growing up, Come, Holy Ghost was THE hymn for Confirmations and was usually sung as the candidates for Confirmation processed up to be confirmed. My mother was active in the choir at the time of my Confirmation and I reminded her every day preceding the event (as if I needed to, right?) that Come, Holy Ghost was my favorite ever hymn and don’t forget to sing it.
The evening of my Confirmation arrived and I anxiously awaited the procession up to the bishop for my reception of the sacrament, ears tuned for ‘my’ hymn. It didn’t happen! It actually disappointed me so much when another, unknown hymn went into play, that I don’t remember much of that day.
Since my own Confirmation, I don’t think I can recall one that did not have Come, Holy Ghost and have always wondered why my mother (she was choir director) changed the hymn at the last minute.
