It was the end of Sept 1970 at the BDA Feast of lanterns, I was approached by Mr Alf Dempster with the offer to join 5 others to form a new DA. (BDA at that time was getting very large). It required 6 members to form a new section, the six being Mr Alf Dempstrer, Mr Fred Sharpe, Mrs Sheila Sharpe, Mrs Doreen Taylor, Mr Colin Ball, and myself Jim Oliver.
