Walkin' on the Sun was released in 1997 as Smash Mouth's debut single, taken from the band's first album Fush Yu Mang. Written by guitarist Greg Camp, the song mixed pop rock with funk and psychedelic influences and became the group's breakthrough hit in the United States. Its opening riff remained one of the most recognisable parts of the track, often recalled separately from the full song. Online, that short guitar figure is now reused as a nostalgic marker for the late nineties, summer confidence and playful retro cool.
