I just had my own personal WhoSampled moment with the closing credits sequence from the Australian music video clip show "Rage", familiar to generations of Australian 20-somethings.

I was actually fast-forwarding through an episode of Rage (to see if there was another episode of QI later on, because I'm of a certain age). And noticed this bit of footage:

I thought "That looks familiar...", so I rewound and watched the clip and I noticed that this chord also appears prominently:

Anyway, it turns out that they used an edit of the Extended Mix of "Speed Your Love to Me" by Simple Minds.

It's always weird when you find a famous sample out of context.
