Some veterans and young Catholics have voiced anger that the Aug. 1 concert falls on the 68th anniversary of the uprising - a day marked with a somber tone.
The city-wide attack ended in the deaths of thousands of Poles and the destruction of the city.
City officials proposed airing a clip about the revolt to allay the veterans' feelings.
Ania Pietrzak, a spokeswoman for concert organizer Live Nation, said Wednesday "it is an important moment in Polish history, so we have decided to remind people of that moment."
