The Drifters first single featuring Charlie Thomas on lead vocal, "Sweets
for My Sweet" reached No. 16 on the Billboard Hot 100 and No. 10 on the
R&B chart, in October 1961. This was one of the few post-1958 Drifters
singles that did not feature a string section. It also featured Jimmy Radcliffe
and four female backup vocalists, all of whom would later have hit records,
Cissy Houston, Doris Troy, Dionne Warwick, and Dee Dee Warwick. The
recording also features an up in front piano provided by the song’s co-writer,
Mort Shuman. (From Wikipedia)
