POPE BENEDICT XVI has criticised his late predecessor POPE JOHN PAUL II's decision to share the stage with American rocker Bob Dylan.
The current pontiff, who took over as head of the Roman Catholic Church following John Paul II's death in 2005, believes rock music is the work of Satan and cancelled the annual Christmas pop concert at The Vatican last year (06).
Benedict XVI was one of John Paul II's closest aides during his time as Pope and was concerned when John Paul II appeared on the same platform as Dylan during a 1997 concert in Bologna, Italy.
Dylan sang KNOCKIN' ON HEAVEN'S DOOR, A HARD RAIN'S A-GONNA FALL and FOREVER YOUNG at the concert.
In Benedict XVI's new book JOHN PAUL II, MY BELOVED PREDECESSOR, the current Pope writes, "There was a reason to be skeptical and I was.
"Indeed in a certain sense I still am today. I have doubts to this day whether it was right to let this kind of so-called prophet take the stage (in front of John Paul II)."
