1977 Gets married and pursues song writingBilly and Maureen were married in 1977 and have 4 children. Billy knew Maureen in his school days. “I had my eye on her,” he said. “Come to think of it, I remember how I first got to speak to her. She has grown into this princess of my dreams." Billy started visiting Maureen and the two of them started going to church youth camps together. Billy remembers “Her mom was very fond of me – it's much easier if the mothers like you." After all these years, he will never forget the nervousness of the moment when he asked her to be his wife.
In the same year Billy became a Christian and took to gospel music instead of following in his brother Neville Nash's pop footsteps. “Gospel singers get their satisfaction from what they are doing and feeling, not from the screeching crowds one sees at pop concerts. Billy has written songs for his brother, Neville. ” I Don't Want To Be A Star” and “Where We Go” were two pop songs that Billy wrote. In 1980, Billy formed the group Humble People, who gained tremendous popularity by playing original music. Two years later the group changed it's name to Wisdom. Their first album together was called Running Back.
