"Walking on the Sun" is a song by Smash Mouth which is a San Jose, California band fronted by Steve Harwell and including Greg Camp, Paul DeLisle, and Kevin Coleman (who subsequently left). This song was Smash Mouth's breakout hit, and it was a big one, staying on top of the US Modern Rock charts for 5 weeks. It has an intentional 1960s retro sound, and in fact is inspired by the 1966 single "Swan's Splashdown" by the Electronic music duo Perrey and Kingsley (Jean-Jacques Perrey and Gershon Kingsley). The mixing of musical genres and eras served them well and helped set the tone for their future hits.
