When Michael Lawrence was 23, he died of ventricular fibrillation, a heart condition.
"It was very hard for all of us, but it's still very hard," Gorme said.
"You don't deal with it, you just go on as best you can. And fortunately, we all held on," Lawrence said.
For a year, the pair mourned. Then they decided to go back on tour, with their surviving son David joining them on stage on the piano.
The pair continued touring well into the 2000s.
During their long career, they toured with Frank Sinatra, threw the first pair of dice in Atlantic City and recorded a lounge version of Soundgarden's grunge classic "Black Hole Sun."
"I'm very thankful that Eydie and I, not only do we have a great love, and a great friendship," Lawrence said.
In addition to her husband and son, Gorme is survived by her granddaughter.
