This heartwarming moment has gone viral. Simon McDermott drives around with his 80-year-old father who has Alzheimer's. Together, they sing their hearts out to "Quando, Quando, Quando," and this song is what seems to 'bring him back,' if only for a few minutes. 

Ted was diagnosed with dementia in 2013 following a long career as an entertainer, performing for the public in pubs and clubs across England.

His video has helped raise more than £57,000 for the Alzheimer's Society just two days after his son set up a Just Giving fundraising page.
