well..mosdef bon scott ac dc is my favorite band probably ever.. i know that seems like hyperbole.. having said that brian johnson may be the quintessential hard rock singer and probably did the greatest fill in job in the history of rock...i'd call any band with malcolm and angus young in it the real ac dc.. but yeah.. I miss Bon Scott A LOT and I didn't even know him..there's something about that scamp; a party on two legs. the real question for me is always the same though: had bon scott put any work into what became back in black because its just hard to believe that brian johnson could step in and knock off back in black.. had they been working on the songs with bon or just writing the music? only two living people probably know the answer to that -maybe three or four- and they ain't speaking. bon died in late february and they cut the album in april.. i think its highly likely bon scott worked on some of the stuff and had some draft lyrics. I mean it seems highly unlikely that back in black was all written without input from bon. highway to hell was written in early 1979 and are we to think that nothing was written for the next 12 months?? i am not knocking the young brothers: they have taken care of bon scott's family. but bon scott's bawdier lyrics were always a bit more clever than brian's, no? its hard to fault brian for the band's evolution though as the young brothers wrote the music..but its reasonable to wonder if ac dc would have evolved differently with bon scott....and thats my 2 cents. one more cent: we do know that phil rudd the drummer was very unhappy after bon died, got into big fights with malcolm and left the band/was fired by early 83.. and thats about all we know for sure.. what is Rudd knew that Bon had had something to do with Back in Black and wasn't comfortable with that? its purely guess work but..
