Background: The Four Tops are a vocal quartet from Detroit, Michigan, USA, who helped to define the city's Motown sound of the 1960s. The group's repertoire has included soul music, R&B, disco, adult contemporary, doo-wop, jazz, and show tunes. Founded as the Four Aims, lead singer Levi Stubbs, Abdul "Duke" Fakir, Renaldo "Obie" Benson and Lawrence Payton remained together for over four decades, performing from 1953 until 1997 without a change in personnel. The Four Tops were among a number of groups, including the Miracles, the Marvelettes, Martha and the Vandellas, the Temptations, and the Supremes, who established the Motown Sound heard around the world during the 1960s.
Context: From the late 1980s, the Four Tops focused on touring and live performances. They recorded only one album, returning again to Motown for 1995's Christmas Here with You. On June 20, 1997, 59-year-old Lawrence Payton died as a result of liver cancer, after singing for 44 years with the Four Tops who, unlike many Motown groups, never had a single lineup change until then. At first, Levi Stubbs, Obie Benson, and Duke Fakir toured as a trio called The Tops. In 1998, they recruited former Temptation Theo Peoples to restore the group to a quartet. By the turn of the century, Stubbs had become ill from cancer; Ronnie McNeir was recruited to fill the Lawrence Payton position and Peoples stepped into Stubbs' shoes as lead singer. Stubbs later died on October 17, 2008 at his home in Detroit. The group was featured in several television specials during this time, including Motown 45, and several by PBS, including a 50th anniversary concert dedicated to the group (available on DVD). The concert turned out to be bittersweet; it featured a brief appearance of the wheelchair-bound Levi Stubbs, and a memorial to Lawrence Payton, announced by Obie Benson. Benson appeared on one more PBS special and died on July 1, 2005, from lung cancer. The final PBS special, titled Motown: The Early Years, featured a message of Benson's passing following the credits. Lawrence Payton's son Roquel (real name Lawrence Payton, Jr.) replaced Benson as the new bass (Roquel could be seen in the pledge break interviews of Motown: The Early Years). Theo Peoples also left the Tops to form his own group and was replaced by Harold 'Spike' Bonhart as lead singer. The group was inducted into the Rock and Roll Hall of Fame in 1990, and into the Vocal Group Hall of Fame in 1999. In 2004, Rolling Stone ranked them #79 on their list of the 100 Greatest Artists of All Time.
