71-year-old Krishna Tamang, left, and Muktinath Regmi, 81, pose for a photograph at the Pashupati Briddhashram, a home for the old, in Kathmandu, Nepal, Friday, Nov. 13, 2015. Each year, Tamang and Regmi roam the neighborhoods of Kathmandu singing traditional Deusi songs celebrating Tihar, the festival of lights, and receiving money in return. Once a group of four friends from the home, only the two of them are now alive and they carry forward the tradition. Tamang lost most of his vision when he was six months old and Regmi acts as his eyes for most parts.
