Denver's first marriage was to Annie Martell of St. Peter, Minnesota. She was the subject of his hit "Annie's Song", which he composed in only ten minutes as he sat on a Colorado ski lift after the couple had an argument. They lived in Edina, Minnesota, from 1968 to 1971. After the success of "Rocky Mountain High," inspired by a camping trip with Annie and some friends, Denver bought a residence in Aspen, Colorado. He lived in Aspen continuously until his death. The Denvers adopted a boy, Zachary John, and a girl, Anna Kate, whom Denver said were "meant to be" theirs. Denver once said, "I'll tell you the best thing about me. I'm some guy's dad; I'm some little gal's dad. When I die, Zachary John and Anna Kate's father, boy, that's enough for me to be remembered by. That's more than enough". Zachary was the subject of "A Baby Just Like You", a song that included the line "Merry Christmas, little Zachary" and which he wrote for Frank Sinatra. Denver and Martell divorced in 1982. In a 1983 interview shown in the documentary "John Denver: Country Boy" (2013), Denver said that career demands drove them apart; Martell said they were too young and immature to deal with Denver's sudden success. Following the property settlement, Denver nearly choked Martell. He cut their marital bed in half with a chainsaw.
