VIDEO: The sound of bagpipes and snare drums could be heard up and down Denver’s Market Street throughout St. Patrick’s Day weekend. "We are raising money for what we do all year long,” said Paulette Diaz, member of Colorado Emerald Society Pipes and Drums. “It’s an honor because we’re honoring our fallen firefighters and fallen police officers and fallen medics.” Colorado Emerald Society Pipes and Drums marching band performed Sunday evening inside the Celtic on Market. It’s not their typical scene. Normally, they play at funerals. Diaz was a Denver firefighter for nearly 27 years. She retired in January and continues to give back through music.
