The song tells the story of a 17-year old girl and her budding interest in "the nightlife". It is told from the perspective of a teenage boy who wishes to ask her out for a date. She refuses any and all of his advances.
The song's B-side is a non album B-side titled "That's It" that features Benjamin Orr on lead vocals.
The single peaked at #14 on the Billboard Hot 100 singles chart in the U.S., but the song was an even bigger success elsewhere. In Canada, the track reached #5, and remains the Cars' highest ever charting single in that country. Similarly, "Let's Go" peaked at #6 in Australia, where it remains The Cars' highest charted hit.
