One good song for a mother-son dance is "I Hope You Dance" by Lee Ann Womack. The song features a mother's wishes for her adult son and emphasizes the importance of taking chances in the name of love.
"He Gets That From Me" by Reba McEntire is another good choice for a mother-son dance. McEntire sings about the characteristics that her son inherited from her, from his knobby knees and pickiness at breakfast to his sense of humor. The song celebrates not only the son's relationship to his mother, but also his love for his father.
"Mama Tried" by Merle Haggard is a humorous choice for a mother-son dance. Haggard sings that his mother tried to raise him well, but he refused to take her advice. "That leaves only me to blame 'cause Mama tried," he sings of the problems in his life.
