CNN —Singer Carly Simon paid tribute to her two sisters, Joanna and Lucy, who died just a day apart of each other this week, both from cancer. Joanna Simon, 85, died of thyroid cancer on Wednesday and Lucy Simon, 82, died of metastatic breast cancer Thursday, Simon’s manager, Larry Ciancia, confirmed to CNN. “I am filled with sorrow to speak about the passing of Joanna and Lucy Simon. Joanna Simon was an opera singer and Lucy Simon was a performer and composer who was nominated for a Tony Award for the score of the “The Secret Garden” musical. “As sad as this day is, it’s impossible to mourn them without celebrating their incredible lives that they lived,” Simon said.
