Long story short: found an app for the iPad that lets you sample different media from different years gone by.
Whilst exploring, I came across this, released in mid-1985. It's apparently a "Teach-Yourself-How-to-Break-Dance" thing starring that kid who dances like Michael Jackson and played second fiddle to Wil Smith.
There are a number of songs included in this package. Most of them sound like they they were poached from the "Electric Boogaloo" soundtrack.
But guess which tune mysteriously appears at the 1:25 mark?
Somewhere Chris and Tina are weeping, for sure....
