I likewise mixed Koko several times. Yeah, she had a way of taking any song & making it sound it like Wang Dang Doodle, but somehow she made that work; she was amazing on stage! Plus, offstage she was a truly sweet lady. (And, while I didn't know her until she was in her fifties, I've seen pictures of her in her twenties - what a babe!)
She will be missed.
