The Backstreet Boys went ahead with a planned performance in Toronto Saturday, but not before the group paid tribute to the victims of this week's terrorist attacks in New York and at the Pentagon.

One of those killed in the destruction of the World Trade Center was Danny Lee, a set carpenter for the group's current "Black & Blue" tour. Lee was on board the hijacked plane that crashed into the north tower. He was returning to Los Angeles after the Backstreet Boys' Boston performances to await the birth of his second child.

The group asked the audience Wednesday night to observe a moment of silence for Lee and the other victims of the attacks in New York, Pennsylvania and Washington, according to the group's publicist.

They also announced it was donating $1 from each ticket to a relief fund established by ClearChannel.com, the tour's sponsor. The fund will raise money for the American Red Cross and other organizations helping with rescue and relief efforts.
