Ok technically this video came out in 1980, but it's pretty much the greatest 70's video ever fucking conceived.
Deep sounding 70's voice over intro? - check
Star Wars sound effects? - check
Colored water "special effects" like the opening credits of Superman: The Movie? - check
Rainbows? And Afros? - OMG check
Seriously I was trashing my Star Wars toys when this thing came out.
