The current group’s manager, Dina Roth, tells the Los Angeles Times that Barbour had lung cancer and died Saturday at his Ventura County home in Simi Valley.

Barbour’s death comes three months after the death of another founding member, his cousin, Bob Flanigan. The two other founding members were Barbour’s brother, Don Barbour, and Hal Kratzsch.

The Grammy-winning Four Freshmen’s hits include “Graduation Day,” ‘‘It’s a Blue World,” ‘‘Mood Indigo,” ‘‘Day by Day,” ‘‘It Happened Once Before” and “How Can I Tell Her?”

The group underwent many personnel changes over the years, with Ross Barbour retiring from it in 1977.
