Help pours in for homeless woman caught on video singing in subway

Help is pouring in for a homeless woman whose singing was caught on video in a Los Angeles subway.

GoFundMe sites have raised about $70,000 for Emily Zamourka, and a city councilman's office is paying her to perform this weekend. 

The 52-year-old taught music after coming to the U.S. from Russia. She suffered serious health problems, and several years ago, her violin was stolen and smashed, taking away her livelihood.
