Paul McCartney calls one of his solo song lyrics meaningless

Paul McCartney recently acknowledged that one of his songs, "Uncle Albert/Admiral Halsey," contains a lyric about "butter pie" that he considers meaningless. He explained that he enjoys surrealist art and words, similar to the style of Lewis Carroll. Despite his comments, McCartney learned that butter pie is a real dish in England, made with potatoes, onions, and butter. He admitted he had never heard of it before writing the song. "Uncle Albert/Admiral Halsey" was a significant success for McCartney, reaching number one on the Billboard Hot 100 in the U.S. It marked his first chart-topping single after The Beatles disbanded.
