T.A Oni was a socialite; he was a member of various clubs such as, West African Club, Ibadan Recreation Club, Lagos Island Club etc. He was the Balogun of Oke-Imesi and the Bada of Igbajo. He had friends from all race, and background, black, white, rich, poor, military, civilian, politician etc. He frequently hosted parties for guests- friends, business associates, Governors etc on his balcony in Goodwill house. He loved to dance and whenever he visited any foreign country, his friends would invite him to series of waltz dancing sessions as he was said to be a great waltz dancer. His social attitude endeared him to his friends and administrators in the Western Region.

T.A Oni included his family in his social activities; he attended cocktails, dinners, and other parties with his older children. Xmas Carol concerts were held annually, for him and a few of his close friends, by the younger children and grandchildren in Goodwill House. This event was taken very seriously by all ,as series of rehearsals usually took place before the day, with a close friend of the family, as the organist. New Year’s Eve (December 31^st) party at Goodwill house (without outsiders) was a “must event” for all his sons and daughters and their families. Every member of the Oni family looked forward to this once a year party. It was usually held in the family sitting room, where everyone enjoyed themselves, the younger children chatted, joked and danced with their older siblings. The youngest children and grandchildren would usually be running wild outside. It was his special way of getting his large family to bond and he definitely achieved that.

On May 10, 1973, T.A. Oni turned 60. He was a great man in the society, by sheer hardwork and determination and to a large extent, it looked like he had fulfilled his life ambition: he had built the first indigenous construction company in Nigeria which compared favorably with any foreign firm; he had been honored by the Queen of England with the Member of the British Empire (MBE) and by the Federal Government of Nigeria as a Member of the Federal Republic Of Nigeria (MFR); he had chieftaincy titles from Okemesi and Igbajo.  Therefore, he chose to celebrate his 60^th birthday in a grand style.

The ceremony lasted for a week, with comedians like Moses Olaiya (Baba Sala), Ebenezer Obey, Sunny Ade performing on different days; customized Ankaras were specially made to commemorate the occasion. Guests from all over the world were invited to wine and dine with him, they included, his long time friends Isaac Ajanaku and Henry Fajemirokun. Also invited were Sir Olateru Olagbegi, the Olowo of Owo with whom he had often played Tennis in his early days, Sir I.S Adewale (Founder of Julius Berger, Nigeria), Professor J.F Ade Ajayi, Vice Chancellor, University of Lagos, Brigadier Samuel Ogbemudia , Chief Israel Adebajo, C.R Harding (M.D of Standard Bank), Business associates from companies; Edward Turner & Sons London, Blackwood & Hodge in Liverpool etc. Congratulatory messages were sent by those who could not attend. The impressive attendance of the occasion was based on his achievements over the years; some of which included the roads he had constructed, the buildings structures he had erected for corporate bodies and individuals, his interaction at the private and Ggovernment levels, especially, his stance at encouraging indigenous contractors to excel.

But as he celebrated his 60th birthday anniversary with grandeur, little did he know that he was bidding everybody goodbye, as he soon fell sick in 1974 and died in Philippines on Saturday, February 15, 1975.
