Gearheads of War

i was excited to see that slash would be performing on guitar hero 3 and that there would be songs both from gnr and velvet revolver.  however, through 7 playlists of 8 i have seen no sign of velvet revolver.  i have checked to make sure that it is not on the game anywhere (through many sites) and sure enough, no velvet revolver.  i wouldnt be posting this though if that was it.  while watching comedy central 2 minutes and 35 seconds ago i heard a song that i liked and saw two guys playing what appeared to be guitar hero 3.  after thinking for a few minutes and singing through the song i realized that it was none other that velvet revolver singing 'slither'.  right as slash popped out of the tv i ran to the computer and started typing this.  

so now i am sitting here wondering, where is it.  i found it a little odd that the song they used on their comercial isnt even on the game.  i would much rather play some good old rock music than play that rediculuosly hard slipnot song
