Kenny Rogers had a vast catalog of songs from throughout his 40-year career -- including more than 45 Top 40 singles -- but there's one song that remained his favorite to perform.

Rogers told The Boot and other reporters in 2016 that 1978's "Every Time Two Fools Collide," originally a duet with Dottie West, was that top tune. "It was, I think, the first duet I had ever done," Rogers recalled. "I loved her, and I thoroughly enjoyed the song."

While "Every Time Two Fools Collide" wasn't necessarily Rogers' most popular single -- though it did reach No. 1 on the Billboard Hot Country Singles chart -- it remained his favorite partially because of the woman with whom he sang it.

"My persona is, I’m more known for "The Gambler" and the Dolly Parton stuff, but that was the song that I loved doing," Rogers explained. "... I think Dottie West is one of the most unappreciated artists ever in country music, and I’m going to do everything I can to get her into the Country Music Hall of Fame."

Rogers died on March 20, 2020.
