Conny (or Cornelia) Froebess performing "Zwei Kleine Italiener" ("Two Little Italians"), the German entry at the 1962 Eurovision Song Contest.

One of the most widely-known songs from that year's contest, and not without reason since, along with the Finnish entry, this was quite possibly the cutest and catchiest song of the bunch (all together now: "O Tina, O Marina...") - helped by a lively performance from 19-year-old Conny, a popular teen singer and actress at the time (according to Wikipedia, she mostly starred in comedy films, where she often played a teenage girl "who craves for independence from her all-too-strict parents", which sounds to me like a German version of Sandra Dee or Annette Funicello).
