More lineup changes followed after Ferbee was involved in an accident and left the group. After Adams died, he was replaced by Jimmy Oliver. Ferbee was not replaced; instead, the voice parts were shifted around. Gerhart Thrasher moved up to first tenor, Andrew Thrasher shifted down to baritone, and Bill Pinkney dropped to bass. This group released several more hits, including "Such A Night" in November 1953, "Honey Love" June 1954, "Bip Bam" October 1954, "White Christmas" November 1954, and "What'cha Gonna Do" in February 1955. McPhatter received his draft letter in March 1954, but as he was initially stationed in Buffalo, New York, he was able to continue with the group for a time. "What'cha Gonna Do", recorded a year before its release, was McPhatter's last official record as a member of the Drifters, although his first solo release ("Everyone's Laughing" b/w "Hot Ziggety") was from his final Drifters session in October 1954. After completing his military service, McPhatter pursued a successful but relatively short-lived solo career with 16 R&B and 21 pop hits.
