After their partnership ended with their final nightclub act on July 24, 1956, the boys went on to successful solo careers and neither would comment on the split nor consider a reunion. They were occasionally seen at the same public events, though never together. On two occasions, in 1958 and 1961, Martin invited Lewis on stage, but the split was too serious for them to reconcile. Later in September 1976, Sinatra surprised Lewis by bringing Martin on live stage, reuniting them after 20 years apart and then in 1989, Lewis attended Martin's 72nd birthday.
