Here are a couple of ads for a January, 1970 showing of ALL THE LOVING COUPLES (1969) at the Cinema Delaware in Albany, NY. Written by screen heavy Leo Gordon, it has yet to make its DVD debut.
Here's a double-bill from May, 1971 at Raleigh's Center Drive-In: THE AMAZING TRANSPLANT (1970) is the weird Doris Wishman film, and PROWL GIRLS (1968) is a Barry Mahon film still MIA on video.
