The Rolling Stones are to give a share of proceeds from a concert in Warsaw to the families of 26 Polish pilgrims who were killed in a coach crash in France.
The Stones are currently on a three-month tour around Europe
The rock legends are to go ahead with Wednesday's gig, which will follow three days of national mourning for the victims of Sunday's crash.
A minute's silence will also be held during the show, organisers said.
Earlier, singer Rod Stewart cancelled a concert scheduled to take place in Gdansk during the mourning period.
The accident happened in the French Alps, near the city of Grenoble.
The coach, which had come from the Szczecin area of north-west Poland, was carrying 51 people, including two drivers.
Most of the passengers were elderly Roman Catholic pilgrims on their way back from the shrine of Notre-dame-de-la-Salette.
The vehicle broke through a safety barrier while going down a steep road before falling into a ravine and bursting into flames.
The Rolling Stones' concert promoter Viva Art did not say how much money was likely to be given to the victims' families.
Tens of thousands of fans are expected at Wednesday's sell-out show at the Sluzewiec Hippodrome as part of the band's three-month European tour.
