It looks like some Keith Urban fans in Massachusetts might have taken the title of his latest tour a bit too literally.

According to Reuters, 46 fans who attended Urban's Raise 'Em Up Tour tour stop at the Xfinity Center in Mansfield, Mass. on Saturday night (July 26) were treated for alcohol-related illnesses, with 22 of them having to be transported to local hospitals.

The Boston Herald reports that many more concertgoers were taken into police protective custody.

“Last evening’s Keith Urban concert was not anticipated to present with the volume of issues handled, but measures were in place to provide appropriate and adequate care and protection to all patrons. As a result, although there was a higher than expected volume, appropriate care was available through the expandable model,” Mansfield Police Chief Ron Sellon and Fire Chief Neil Boldrighini said in a joint statement Sunday (July 27).

“The large number of medicals in a shortened time of approximately three hours caused the activation of a phase one EMS plan utilizing ambulances from five mutual aid communities. Police dealt with a steady stream of intoxicated persons as well, resulting in over 50 people being taken into protective custody and a number of others arrested for alcohol-related issues.”

Authorities said that some of the medical problems were caused by intoxicated fans passing out and injuring themselves. Live Nation spokeswoman Jacqueline Peterson points out that more than 18,000 fans were in attendance.

“Our team works hard to offer a great concert experience for fans," she states, "and an overwhelming majority of fans enjoyed the concert.”

As did Urban himself. He posted the following video to Twitter after the show, calling the crowd "nutso."

The Raise 'Em Up Tour runs through Sept. 13 before wrapping up at the Washington State Fair.
