MARY LOUISE KELLY, HOST:
This week, we're remembering some of the more than 500,000 people in the U.S. who have died from COVID-19 through the music that gave their lives meaning. We're calling our tribute songs of remembrance. Today, Lionel Mares shares stories about his mother, Maria Angelica Mares, of Sun Valley, Calif. He says the song his mom loved was "I Walk The Line" by Johnny Cash.
