Horace Hartley's leaving party at the Rec Club

This must have been about 1970. Horace had a wife (Margery?) and adopted daughter Ruth, but I haven't found them in the photos except perhaps for the back of Mrs Hartley's head. Jane took the photos for Mwadui News. I've put some names in the captions, with (?) where I'm guessing. If you recognise other people please comment beneath the photos and I'll update the captions.
