Let there be Light

This is stuck in my head, only cause its an acdc song of course, not in the biblical sense, god forbid, Bon Scott did a much better job!
And i know the title is let there be rock, but i always remembered it as light for some reason.
I managed to get tickets for the concert and it was fab,  there were a million people, and angus is still rockin non stop. So in this theme i will post a utube vid..., this is one of my fav's. Let there be rock
ahh the good old days, and i couldnt leave this one out, so here it is...
its a long way to the shop if ya wanna sauage roll!
