国際プロレス
In January 1967, the Kentuckians showed up in Japan's International Wrestling Enterprise. They challenged Antonio Inoki and Hiro Matsuda for the NWA World Tag Team Championship twice but lost by disqualification both times, although Inoki was able to pin Smith in the second fall of the second match. (Matsuda later recommended Smith's daughter Rockin' Robin to work for All Japan Women's Pro Wrestling in the 1990s).
