Astro Daters and Grindhouse Bumpers

Background
This is a fan nickname given to probably the single most infamous set of theatre snipes ever made, created by the National Screen Service in the late 1960s.

Variants:

FX/SFX: The psychedelia in the background, and the text movement.

Music/Sounds: An abridged version of the 1968 go-go-like tune called "Funky Fanfare" by Keith Mansfield. Sometimes it's silent.

Availability: Various, ranging from uncommon (Our Feature Presentation and Prevues of Coming Attractions) to extinct (several of the lesser-known Daters). Used at drive-in theaters by various companies in the 1960s and 1970s. Made a surprise reappearance on certain Robert Rodriguez and Quentin Tarantino films Kill Bill: Volume 1 (2003), Machete Kills (2013), and the 2007 double feature Grindhouse (Planet Terror/Death Proof).

Legacy: This is a cult classic among moviegoers.
