As long as songwriter Jim Holvay supplied more material of the same high quality as "Kind of a Drag," the Buckinghams were sitting pretty. Holvay cowrote "Don't You Care," "Hey Baby (They're Playing Our Song)," and the pseudo-psychedelic "Susan"; each proved to be a major hit for the band. The group's R&B roots surfaced on a vocal arrangement of Cannonball Adderley's jazz standard "Mercy, Mercy, Mercy," their second-biggest hit.
The Buckinghams' fortunes, however, soon changed drastically. Although amonst the top-selling rock groups of 1967, they managed only one hit after early 1968, and had disbanded by the end of 1970. Two of the original members, guitarist Carl Giammarese and bassist Nick Fortuna, have since revived the Buckinghams for various oldies tours.
