First recorded (as a demo) by Donald Fagen & Walter Becker with Flo & Eddie (1971).
Hit album version by Steely Dan (1975).
From the wiki: “This was the first song Steely Dan recorded, predating Steely Dan’s debut album Can’t Buy A Thrill. They first put it to tape in 1971 in a version with backing vocals by Flo and Eddie (Mark Volman and Howard Kaylan) of The Turtles.
“The song tells the story of a man who shows 8mm porn movies to young boys. With its lilting melody and catchy chorus, it’s easy to misinterpret the track as a playful kids’ song about going to the movies. At least one theater operator in the United States used the chorus of this song on the speakers prior to the coming attractions (without understanding the, uh, significance of the lyrics). ”
