My mum was a poor singer but would often sing snatches of songs (or - annoyingly - advertising jingles) as though these small pieces were 'earworms'. This was pre-dementia - just a little habit she had and she'd often match her song to where we were or what we were doing. e.g. whilst driving through Chapel-en-le-Frith she'd sing, 'Going to the Chapel...' and seeing waterlilies on a pond she's burst into, 'We'll drink a-drink a-drink, to Lily the Pink a-pink a-pink...!' etc. My daughter used to joke that Gran had a song for every occasion
As dementia set in she couldn't stand music of any type - didn't want to listen to anything, hated the singers who came to the care home, always saying it was an awful racket and she wished they'd shut up. So sad. So unfortunately music therapy wasn't for her. She did still retain one snatch of a song which I will never forget and was often heard muttering: 'It's my party and I'll cry if I want to...'
