"Sunglasses at Night" is a song by Canadian singer Corey Hart. It was released on January 21, 1984 as the first single from his debut album, 1983's First Offense, and became a hit single in the United States, officially rising to number 7 on the Billboard Hot 100 during the week that ended on September 1, 1984.[1] The song combines an unflagging synthesizer hook, characteristic arpeggio, rock guitar and cryptic lyrics. AllMusic has since described it as "an instant classic with its distinctive melody and catchy chorus".[2] According to co-producer Phil Chapman, the recording sessions for the album took place in a studio whose air conditioning/heating vents were directly above the mixing console. Air from the vents blew directly into the faces of the control room personnel, so they often wore sunglasses to protect their eyes. Hart, working on a new song, began to improvise lyrics that included the line "I wear my sunglasses at night."
