The internationally acclaimed Irish dance troupe Riverdance will be among those performing for Pope Francis at the August World Meeting of Families in Dublin, organisers said July 19.

The group – which has been seen by some 25 million people worldwide – will be one of the main acts at a Festival of Families on August 25 before an expected 80,000 people at Croke Park stadium in Dublin.

Brenda Drumm, spokeswoman for the World Meeting of Families, said she expects people from 116 countries to participate in the event, at which the Pope will preside. Pope Francis also will hear testimony from families from India, Iraq, Ireland and Burkina Faso on topics as diverse as the effects of technology on family life and the value of families forgiving one another.
