Funny what you can find on internet.
I've never seen that before, many videos from AC/DC rehearsing in an L.A. studio for "Flick of the Switch" in Oct 1983:
AC/DC covering Rory gallagher's "Messing with the kids": (music starts around 3:50)
"Guns for Hire"
"Flick of the switch"
HUNDREDS of live/ rehearsals videos from AC/DC HERE
Probably my favorite AC/DC song " Touch too much" with Bon Scott, Radio Edit recorded for the BBC a few days before Bon's passing:
So long... Bon
