Wonderful song. She was a great artist who never broke through. This is a perfect release for its time though. Bad management. Sadly she had all the excesses and tragic end of a doomed rock star.
Was there ever any (credible) data that Brian ever dabbled with using heroin which, by 68, became a choice drug of so many British rock stars within and around the Stones?

Heroin rarely leads anywhere productive, and she was hooked on it from the early days. And, birds of a feather, they do flock together. If Brian wasn't doing heroin per se, he certainly was doing parallel substances as "prescribed" by his Dr Feelgood.
