In February 1967, Wilson announced that "Vega-Tables" would be the lead single from "Smile", although he had only recorded the "cornucopia" demo of the song at this point. To taunt the record company, Wilson staged a mock promotion of the "Vega-Tables" by holding a photoshoot at the Los Angeles Farmers Market, where he posed in front of a fruit and vegetable stand. Parks was against having the song as the album's single. He later commented, "I am sure I would not have wanted 'Vega-Tables' to be given too much emphasis. For "Smile", that celebrated collaboration, to be dependent on a commercial release of 'Vega-Tables' as a single, was to me tremendously ill-advised, wherever it came from." In early April, the band spent at least eight studio dates recording "Vega-Tables" before embarking on a US tour on the 14th of the month.
