Kesha honored her very special connection with Dolly Parton at a concert just hours after the country star's death. The "Tik Tok" singer's mother, Pebe Sebert, co-wrote "Old Flames Can't Hold a Candle to You," which Parton popularized in a hit 1980 cover. Kesha later sang it as a duet with Parton on the pop star's 2017 album "Rainbow," which was made while she was involved in a highly publicized legal battle with music producer Dr. Luke. Kesha paid tribute to Parton by performing the song and explaining her familial connection during a Pittsburgh tour stop on Tuesday. 🎥: @ForJoolia #Kesha #DollyParton #Concerts
