In the United States, Lulu is often thought of as a one-hit wonder, having scored a memorable number one hit in 1967 with the bittersweet and evocative "To Sir, With Love" without ever duplicating that feat (though she did land three other singles in the Top 40). In the United Kingdom, however, the Scotland-born vocalist had already scored a handful of hits when "To Sir, With Love" was released as the B-side to "Let's Pretend." There, she would become an enduring star in pop music, on television, on-stage, and in the movies, thanks to her strong, versatile voice and sunny disposition. Her 2002 duets album, Together, reached a career-high number four in the U.K., and Lulu released her 15th studio album, Making Life Rhyme, in 2015. She continued to appear on-stage and onscreen into the 2020s.
