I really like that one too, Dave's Wife. Hildebrand wrote it for his son to introduce him to different rhythms. I went to Hildebrand for my usual music lesson, one day, and he showed me the cupboard in Paddy's room. The drawers were labled: "Socks", "Jumpers", "Underwear" and "Kittens" (the old label crossed out). Sure enough, inside the drawer was Sooty with her 5 babies. I don't know what would have happened if she'd had a different number. He'd have had to abandon the idea of a 5/4 song.
Gris, the "dog who lives over the way" was called Grisley because he looked like a bear - Gris for short.

That's all there was to "Sooty the Cat" but Hildebrand would be delighted if you wrote more about Inky. Please post them here. We'd love to have them. Paddy would have been thrilled too. Thank you so much, Dave's Wife, for sharing my delight in this song. Cheers, Joy
