On March 21, 1987, Martin's son, Dean Paul (formerly Dino of the '60s "teeny-bopper" rock group Dino, Desi & Billy), was killed when his F-4 Phantom II jet fighter crashed while flying with the California Air National Guard. A much-touted tour with Davis and Sinatra in 1988 sputtered. On one occasion, he infuriated Sinatra when he turned to him and muttered "Frank, what the hell are we doing up here?" Martin, who always responded best to a club audience, felt lost in the huge stadiums they were performing in (at Sinatra's insistence), and he was not interested in drinking until dawn after performances. His final Vegas shows were at Bally's Hotel in 1990. There he had his final reunion with Jerry Lewis on his 72nd birthday. Martin's last two TV appearances involved tributes to his former Rat Pack members. On December 8, 1989, he joined many stars of the entertainment industry in Sammy Davis, Jr's 60th anniversary celebration, which aired only a few weeks before Davis died from throat cancer. In December 1990, he congratulated Frank Sinatra on his 75th birthday special. By early 1995, Martin had officially retired from performing.
Martin, a life-long smoker, was diagnosed with lung cancer at Cedars Sinai Medical Center on 16 September 1993. He died of acute respiratory failure resulting from emphysema at his Beverly Hills home on Christmas morning 1995, at age 78. The lights of the Las Vegas Strip were dimmed in his honor.
