In 2009, rising country music star Sarah Darling spent days at her grandfather’s hospital bedside as he battled a serious illness. A spiritual man, he comforted her greatest fear of him succumbing to the fight by sharing his thoughts on the meaning of life, and what happens when someone leaves this world. Forever moved by what she heard in those precious moments, Darling later sat down with Nashville songwriters Dave Robbens and Billy Austen and wrote the song, Knowing What I Know About Heaven, never knowing years later, internationally-known Christian recording artist and former lead singer of the Gaither Vocal Band, Guy Penrod, would make it be heard by millions around the world. In celebration of the song’ success, Darling and Penrod will perform the song together as a duet for the very first time at the 2013 Inspirational Country Music (ICM) Awards on October 24, 2013. Penrod is nominated in the “Entertainer” category at the awards.
