According to Rolling Stone magazine, the Drifters were the least stable of the great vocal groups, as they were low-paid musicians hired by George Treadwell, who owned the Drifters name. There have been 60 vocalists in the history of the Treadwell Drifters line, including several splinter groups by former Drifters members (not under Treadwell's management). These groups are usually identified with a possessive credit such as "Bill Pinkney's Original Drifters", "Charlie Thomas' Drifters", etc. There are two notable versions of the Drifters. The first classic Drifters, formed by Clyde McPhatter, was inducted into the Vocal Group Hall of Fame as "The Drifters" or "The Original Drifters". The second Drifters, featuring Ben E. King, was separately inducted into the Vocal Group Hall of Fame as "Ben E. King and the Drifters". In their induction, the Rock and Roll Hall of Fame selected four members from the classic Drifters, two from the second Drifters, and one from the post-Treadwell Drifters.
According to the Vocal Group Hall of Fame, "Through turmoil and changes the (original) Drifters managed to set musical trends and give the public 13 chart hits, most of which are legendary recordings today." Matching that feat, subsequent formations of the Drifters managed to give the public 13 Hot 100 top 30 chart hits.
