The bus crash happened Sunday in the French Alps when 50 people were returning to Poland after a visit to a Catholic shrine. Twenty-six people were killed and another 24 were injured.
The Rolling Stones and concert promoters donated an undisclosed share of the concert's proceeds to victims' families, NME.com reported Tuesday. Stones front man Mick Jagger asked the Warsaw crowd to observe a minute's silence during the show.
The Stones' Warsaw concert began shortly before the end of three days of official mourning for the bus crash victims.
