I disagree, actually. I think Bon Scott-era AC/DC is horrendous. Every song they ever did with the guy sounds exactly the same. With one exception (that I can remember): a slower song called "Ride On." Too bad that song sucked too.
There's really just nothing even remotely good about Scott's voice. Which isn't to say that Johnson's is much better, but I guess I personally do find it preferable.
