Which Frank and Nancy Sinatra duet was a 1967 Billboard Hot 100 No. 1?

The Frank and Nancy Sinatra duet that became a 1967 Billboard Hot 100 No. 1 was “Somethin’ Stupid.”

Released on Reprise Records, the recording paired Frank Sinatra with his daughter Nancy. It topped the Billboard Hot 100 for four weeks beginning April 15, 1967, making it one of the era’s most recognizable family duets. The song was written by C. Carson Parks, who had recorded it with his wife as Carson and Gaile.

The performance is deliberately understated: father and daughter trade gentle vocal lines over a polished pop arrangement rather than staging a dramatic duet. That intimacy helped distinguish it from Nancy’s solo hits, including “These Boots Are Made for Walkin’.” “Summer Wine” is also associated with Nancy Sinatra, but her well-known version was a duet with Lee Hazlewood, not Frank.
