Parkinson's disease cant diminish their song

Fed up with her voice weakening because of Parkinson’s, 65-year-old Mags Blackwell decided to sing about it.
Part spirit-lifter, part exercise, part scientific experiment, the singing group Blackwell formed with a friend at Lee First Congregational Church works to mollify what one woman called an "invasive, elusive" disease.
