Help with a movie from the 70's?

Does anyone recognize the film where this line was used over and over by the Dad in the movie? The line was variations of "What's the story, Ritchie?"

There was a wedding in the movie and a womanizing groom or best man. And the father was always trying to figure out what his son was doing and kept asking, "So, Ritchie, what's the story?"

The film was probably from the 1970's or later. I thought one of the actors was James Caan but checked his movies and didn't recognize a title.

Just one of life's little "driving me crazy" moments.

Hope that line stuck in someone else's memory bank.

The Death of Ritchie with Robbie Benson???

I THINK IT'S
LOVERS AND OTHER STRANGERS 1970 STARING RICHARD CASTELLANO AS FRANK VECCHIO

HOPE THIS HELPS

Lovers and Other Strangers sounds right.

Thanks so much for your good memory.
