@cbsnews: Kesha paid tribute to Dolly Parton with a cover of "Old Flames (Can't Hold a Candle to You)," a song her mother co-wrote and that Parton took to number one in 1980. “For those of you who don’t know, I come from a long lineage of songwriters and before I was born, my mom actually wrote a song for Dolly Parton. And that song bought us a house, like a roof. That song put me through school,” Kesha told the Pittsburgh crowd on Wednesday. #dollyparton #kesha #concert #pittsburgh
