Woohoo! it's the rebel himself...Lemmy! What a cool cameo appearance.
Another band that gets coined as an AC/DC clone is Rose Tattoo. I don't find them to be as close a clone as Airbourne or Stripwired. Like you said, AC/DC's simplistic formula worked and there is still plenty of room for more simplistic bands. The musical material is still original, that's what counts....
