Mercury sued, claiming it had sole rights to any spelling of the group's name, and the Dell-Vikings briefly became The Versatiles, with singles being billed to "Kripp Johnson and the Versatiles" or "Chuck Jackson and the Versatiles". The group broke up, with Chuck Jackson going on to a successful solo career. Meanwhile, the original group had began to fall apart. Gus Backus was re-stationed, leaving the group a quartet. They broke up soon after. Quick restructured the group with new talent from the Pittsburgh area -- Willie Green, Douglass White, Billy Woodruff, and Ritzy Lee. By the end of 1957, with the breakup of the "Dell" Vikings, Kripp Johnson returned to the original group, making them a sextet. They signed to ABC-Paramount. While the nucleus of the group was back, they weren't able to chart any more hits, and the group split up in 1965.
In 1980, Kripp Johnson restarted the "Dell" Vikings with Dave Lerchey, 1960s member Ritzy Lee, and new member John Byas. Norman Wright rejoined this group in 1990. In the Del Vikings, Jerry Williams was replaced by Herbert McQueen.
Frank "Mingo" Ayers would replace William Blakely in the early 80s. He suffered some health problems after a short time; Henry "Dickie" Harmon would tour as a sub, and following Ayers' recovery, became a permanent member, replacing Herbert McQueen. The group lost its last original member, Clarence Quick, when he died in 1985. His place was taken by Lloyd "Butch" Phillips, and Louis Velez took over bass vocals. They continued recording, and released an album in 1991 for BVM Records entitled Rock and Roll Remembered. Ayers would later be out of the group; the group would reorganize with bassman Les Levine entering. The lineup then became Velez, Martinez, Les Levine, Ron Coleman, and Reggie Walker. Frank Ayers died in 1999; Dickie Harmon is a member of The Teenagers. After a long battle with Illness, "Sweet" Lou Velez died on May 31, 2008. Shelly Wengrovsky now completes the five-man quintet.
Kripp Johnson died in 1990. His group (John Byas, Dave Lerchey, Norman Wright, and Ritzy Lee) continued to perform at major Resorts in the US, Canada, Caribbean, and major Cruise Lines and various Casinos. After the death of John Byas in 1999, Norman Wright left, and reformed another group with his sons Anthony Wright and Norman Wright, Jr., and friend Mike Machado. Dave Lerchey retired but occasionally performed with this group (Lerchey died on the 29th of January 2005). This group was featured on the PBS special Doo Wop 50 in 1999, with Dave Lerchey.
The group's biggest hits have retained their popularity as notable oldies, with "Come Go with Me" being used in such films as American Graffiti, American Hot Wax, The Hollywood Knights, Diner, Stand By Me, and Joe Versus the Volcano.
