As Dean Emeritus (and hymnwriter) Robert Willis of Canterbury Cathedral says, music can help worshippers remember words to hymns such as "O God Our Help in Ages Past". I'd add that unfortunately a lot of older people have hearing loss (partially from doing too much music), and also that there are a good number of weepy hymns, however, just the reciting of liturgical words, keep us all connected and also I am sure those with dementia. Thanks for this relevant presentation.
