In February and March 1966, Wilson began recording an unfinished song he wrote with Asher, "Good Vibrations", between sessions for "I Just Wasn't Made for These Times" and "God Only Knows". Asher recalled that the song was conceived in response to Capitol's demand for a new single. Brian ultimately delivered "Sloop John B" to the label instead, and to the band's disappointment, chose not to include "Good Vibrations" on the album. The track was replaced by "Pet Sounds" as indicated by a Capitol Records memo dated March 3. Johnston and Jardine later expressed regrets with Wilson's decision, as they felt that including "Good Vibrations" would have bolstered the sales of "Pet Sounds". However, the song was not completed until many months later, in September, after much reworking.
