Cliff Williams

Three members who left the band at various points during the 'Rock or Bust' tour have returned.

Whatever the band was doing in the city last year, it appears the retired bassist was there for at least part of it.

AC/DC's bass lines aren't the most complex, but you still need to be awesome to play them.
