 The Dean's List with Janice Dean. A rock star who picked up a fan as he was heading to his concert in England makes today's Dean's List. Chris Martin, the lead singer of the band Coldplay, made Sondra Glenn's day in an incredible act of kindness. Sondra has osteoarthritis and as a result has a hard time with mobility. She was on her way to a festival where Coldplay was performing but struggled to even get to the grounds of the show. Taking a moment to rest against a fence, she thought about going home.
