Ed Sheeran's tour of North and South America has been roiled by the decision this week to drop Macklemore as an opener because of the rapper's onstage pro-Palestinian comments. Since then, all of Sheeran's other supporting acts have dropped out, including a group that plays with Sheeran during part of the show.

Sheeran, who is scheduled to perform Saturday in Philadelphia, said the decision to cut Macklemore from the Loop Tour was the promoter's, not his own. The "Thrift Shop" rapper exclaimed "Free Palestine" during the Sept. 5 date in New Jersey.
