"Du Kannst Nicht Treu Sein" (Hans Otten - Gerhard Ebeler) English translation, "You Can't Be Faithful" by Die Metropol-Vokalisten (Wilfried Sommer, Günter Leider, Peter Purand, Richard Westemeyer and Kurt Bangertof) was a big hit in Germany in 1935.

In 1948 Ken Griffin at the Hammond dominated roller and skating rinks for years. The instrumental single peaked at number two on Billboard.

Vocalist, lyricist and actor Jerry Wayne sang the Hal Cotten English lyrics over the Ken Griffin instrumental and topped the charts later in 1948 with "You Can't Be True, Dear" (Griffin - Cotten - Otten).
