Can anyone put a date on the attached photo? Just the year would do.

We had got to know the lady in the picture as the "Susie" of Susie's Saloon over countless visits over many years. When we arrived for this visit, she told us she was leaving and we were invited to stay on after hours for her leaving do and party all night.

Does anybody remember her and\or when she left, I'm trying to date this picture for a tribute to an old dear friend who died yesterday?

Thanks for any help on this
