Wilson started having increasing doubts about the "Smile" project and showing signs of worsening mental health during the latter months of 1966. After he began suspecting that his father may have planted a listening device in his home, he insisted on holding business meetings in his swimming pool. He also suspected that Capitol was withholding payments from the band and instructed Grillo to conduct an audit of the label's financial records. Discrepancies were soon found. On February 28, 1967, the band launched a lawsuit against Capitol that sought neglected royalty payments in the amount of $250,000 (equivalent to $ in ). Within the lawsuit, there was also an attempt to terminate their record contract prior to its November 1969 expiry. Following the suit, Wilson announced that the company would issue "Vega-Tables" as the lead single from "Smile".
