A few weeks before the documentary dropped on April 17, Beverly said Beyoncé's team called him and played him her cover.
"I was blown away. It's a blessing," the 72-year-old singer said.
Beverly's song — about a relationship coming to an end — has become an R&B classic beloved by generations and is a staple in the black community. Beyonce's version has also become a hit, leading to the #BeforeILetGoChallenge where fans upload videos to social media of themselves dancing to the track.
"Other people have done my songs, but the way she did this was in a class of its own," Beverly said. "She's done something that has affected my life."
