"Some Like It Lukewarm"

According to Andrew Sandoval's The Monkees: The Day-by-Day Story of the 60s TV Pop Sensation, "Some Like It Lukewarm" - the fifty-sixth episode of The Monkees series (and the twenty-fourth of the second season) - was broadcast fifty years ago to-day (4 March 1968).  It was written by Joel Kane and Stanley Z. Cherry, directed by James Frawley, and featured the songs "The Door into Summer" and "She Hangs Out."  Sandoval describes the plot as: "When the group enters a mixed-gender 'rockathon' Davy learns that band contests can be a drag."
