Because he's Cliff
Because the Lead guitarplayer of AC/DC is suffering from Alzheimer's disease and the group is on its last legs. (singer is getting deaf and rhythm guitar has died a while ago)
Think of it as a tribute to Cliff's bass, which has been used intensively by him for forty years and still stands it's ground. If that's not a quality test,......well, than I don't know.
Swink thanks for clearing this up !
When you put it in that perspective it makes sense... it’s a long quality test
I did not know, I knew for his brother Malcom and the singer but not Angus
