Country singer Garth Brooks often puts a lump in his fans' throats with tender ballads. However, when a song moves the crooner himself to tears, you should grab the tissues. Brooks choked up during his 2014 "Good Morning America" performance of "Mom." Host Robin Roberts and the audience bawled along with him.

"It should have been written about 50 years ago," Brooks said introducing the song. "It's a conversation between God and this unborn child about ready to go down to Earth, and when God describes what a Mom is ...whoo! It kills me." The singer needed to compose himself a few times during the performance, as tears filled his eyes.

According to the country music news site Taste of Country, Brooks lost his own mother, Colleen, to cancer in 1999. She witnessed her son reaching soaring heights in the music industry and became a grandmother to Brooks' daughters before she passed. Colleen earned country music success of her own before becoming a mom to a superstar. During the 1950s, Capitol Nashville signed the young Colleen Carroll, where she released several single while singing at the "Ozark Jubilee."
