What does it mean?

...well, absolutely nothing unless you're a fan of Little Shop of Horrors. But it's a funny sound, a funny song and very much a part of Howard Ashman's legacy.

I’m Howard’s sister, Sarah and I hope you’ll join me here as I write about Howard Ashman – the man and the artist. Below is a photo from our family album. I don’t remember whether it was Halloween or a backyard production we were preparing for. It doesn’t matter any more, what remains is the photo and the memory of a brother who always had my back, who drew me into a world of imagination – and who was damn good with a makeup brush.

Da Doo - it means we're going to have Some Fun Now.
