What a wonderful treat that was. Anna has a voice more beautiful than Joan Baez, accompanied by a Kiwi sense of humour and an amazing ability to sing in just about genre and any accent.
And she did this all while her two-year-old daughter, Matilda, was determined to steal the show, along with all our other singing, dancing toddlers at Pacific Gardens!
Then came the potluck, attended by more than 50 - or maybe it was 60. I lost count. I do know we almost ran out of plates and cutlery, which is saying something.
And what a feast. We crowned it off with Myriam's beautiful, scrumptious cake, plus loads of yummy desserts, with everything from fresh raspberries and whipped cream to apple crumble.
We had speeches from founders, residents, and friends, including Chuck Durrett, the architect who brought cohousing to North America from Denmark, and who's working on cohousing projects in Vancouver and on the island.
I have only one worry, though - how will we top this for our fifth anniversary next year?
