After leaving office, Lindsay returned to the law, but remained in the public eye as a commentator and regular guest host for ABC's Good Morning America. In 1975, Lindsay made a surprise appearance on The Tony Awards telecast in which he, along with a troupe of Celebrity male suitors in tuxedos, sang "Mame" to Angela Lansbury. He presented the award for Best Director Of A Play to John Dexter for the play Equus. Lindsay also tried his hand at acting, appearing in Otto Preminger's Rosebud; the following year his novel, The Edge, was published (Lindsay had earlier authored two non-fiction memoirs): New York Times, in its contemporary review of the novel, said it was "as dead-serious as a $100-a-plate dinner of gray meat and frozen candidates' smiles." Attempting a political comeback in 1980, Lindsay made a long-shot bid for the Democratic nomination for U.S. Senator from New York, and finished third. He was also active in New York City charities, serving on the board of the Association for a Better New York, and as chairman of the Lincoln Center Theater. On his death, New York Times credited Lindsay with a significant role in the rejuvenation of the theatre.
