Honestly, I always thought that Kristoff would be standing here to talk about me.” He elaborated on their close relationship: “When Kristoff was born I held him in my arms, just like this, and he was the most remarkable little baby I’d ever seen.

He taught me how to laugh and play. We did everything together.” After the sermon, his daughters led the family out, with the song ‘Somewhere Over the Rainbow’ playing behind them.
