Country trio Lady Antebellum and Janet Jackson have cancelled their upcoming concerts at the Indiana State Fair following Saturday's stage collapse disaster.
Like many Americans, the Need You Now hitmakers and Jackson watched in horror as scaffolding and a lighting rig came crashing down during a sudden storm just before duo Sugarland were set to take the stage.
Five people were killed in the tragedy and more than 40 others were injured.
In a band statement, Lady Antebellum, who were scheduled to perform on Friday, state, "We were so sad to hear what happened and have kept the families of those injured and especially those that lost their lives in our prayers."
And Jackson, who was scheduled to perform at the fair on Wednesday, has also scrapped her appearance.
Maroon 5 and Train are planning to go ahead with their show on Thursday - but it will be staged elsewhere.
And Maroon 5 guitarist James Valentine tells Billboard.com he has been struggling with the decision: "It just doesn't seem like the right sort of atmosphere... It's such a tragedy."
Maroon 5 are hoping to perform a benefit show at another venue for the families of the stage collapse victims.
