From Adams' fourth studio album, Reckless, this is one of his most recognizable and popular songs.
In a 2008 interview with thecelebritycafe.com, Adams said: "I think 'Summer of '69' — I think it's timeless because it's about making love in the summertime. There is a slight misconception it's about a year, but it's not. '69' has nothing to do about a year, it has to do with a sexual position... At the end of the song the lyric says that it's me and my baby in a 69. You'd have to be pretty thick in the ears if you couldn't get that lyric".
