There were actually two different songs entitled "The Peppermint Twist" that charted late in 1961--The one by Joey Dee & the Starliters was the bigger hit, but the one by Danny Peppermint & the Jumping Jacks also charted--I'd link to it if it was on Youtube.
By 1966, the Twist had been passe for years, although something called the Afro Twist would soon be seen on dance floors. I did hear a few Yanks on the British rock stations, including Mitch Ryder & the Detroit Wheels' version of Little Latin Lupe Lu.
In both England and France, the Mamas & Papas' "Monday, Monday" was a big hit. And in Italy, the Dikdiks' Sognando la California (California Dreaming), their version of a big Yank hit, could be heard on the rock stations. In Italy, I also heard Juanita Banana by the Peels on a rock station.
