With one gap left to fill on the package and his then-current single "Clinging Vine" working its way up the charts, Vinton requested that Epic round out the compilation with "Mr. Lonely" (previously featured on his debut vocal album Roses Are Red) and issue it as his next single in conjunction with the album. This rare gambit of reissuing and promoting an older album track paid off as "Mr. Lonely" gave Vinton his fourth, albeit last, No.
As Vinton's current hit "Clinging Vine" was nearing completion of its packaging, he suggested to Epic that they enhance the compilation by adding "Mr. Lonely", a track from his earlier album Roses Are Red, and release it as his next single alongside the album, which ultimately led to him achieving his fourth, albeit last, No.
