Adam Sandler is setting the record straight on the meaning behind a scathing lyric in his “SNL:50” song. During the 50th anniversary special of “Saturday Night Live,” the comedian, 58, sang an original track titled “50 Years.” Sandler co-wrote “50 Years” alongside “SNL” writer Dan Bulla. In the track, the “Happy Gilmore” star belted out: “50 years of finding out your favorite musician is antisemitic.” During an interview with Vulture, Sandler was asked if he had a certain musician in mind when writing the line.
