This appears to be an advertisement for the July 20, 1976 Dolenz, Jones, Boyce & Hart concert at Yubin Chokin Hall in Tokyo, Japan. The Tokyo show was recorded and released as a vinyl LP set in Japan in 1981. The live album was never given a formal release in the United States or elsewhere until 1996, when it was issued on compact disc by Varese Vintage.
Can any of our Japanese friends help with a translation?
