They took on the name the Four Mints and crossed over into popular music and R&B in 1954 and 1955. They'd always listened to the Black R&B vocal groups of the period and proved good -- even inspired -- students: unlike, say, the Crew Cuts, the Four Mints didn't "bleach" out the sounds that they learned to create, but kept them intact even as they made them their own. They were, in many respects, the group equivalent of the phenomenon that Sam Phillips claims to have been searching for, a white man who could sing Black music.
What's more, they were good enough to get bookings far outside of Center, even managing to cross paths with Elvis Presley in the process, and even getting his future drummer, D.J. Fontana, on the skins for some of their gigs in Louisiana. They cut a handful of songs for Lin Records in Gainesville, Texas including "Night Air" and "Little Mama Tree Top" (the latter unissued for 40 years). Although sometimes identified, for convenience's sake, as a doo wop group, the Mints were more animated than most of the acts to which the name is usually applied -- their models were groups like the Treniers, most of all, more so than the balladeer-type outfits usually called doo wop groups.
The Four Mints left Lin after just a few months for the much larger Decca label in 1956. They failed to generate any hits, but Decca's promotional efforts on their behalf and the resulting exposure gave them the intro the needed to break out of the south and become a national act. They followed their idols the Treniers into the same Las Vegas clubs and remained popular for years. McSwain left the quartet in 1960. He was replaced, and the group lasted for another two years, breaking up in 1962. ~ Bruce Eder, Rovi
