TULSA, Oklahoma - Hours before U2 takes the stage at the BOK Center, some fans are already lined up.

This show will be the rock band’s kickoff to its eXPERIENCE & iNNOCENCE world tour.

The general admission line was set up across from the area Tuesday, but some die-hard fans have been waiting since Saturday.

BOK Center General Manager Jeff Nickler says more than 18,000 fans have sold out the Wednesday show.

This is the first time U2 has played in Tulsa in 35 years – the last time was in 1983 at the Brady Theater.

To make the occasion, “No Name” signs were put up near the BOK Center, referencing the band’s hit song, Where The Streets Have No Names.

Tulsa’s Circle Cinema also premiered a documentary on the band Tuesday.

Filmmaker David Barry says Dream Out Loud explores the impact of the band’s music on listeners.

“People come from all around the world to come here to see U2 launch their tour,” said Barry.  “That has become just as important to them as the actual band…that chance to see each other and spend time together.”

The concert starts at 8:00 Wednesday night but doors open at 6:30 p.m.

The BOK Center urges anyone going to the show to leave plenty of time to get to the venue, saying it make take a little longer than normal to get there due to construction.

There is no opener for the show and the BOK Center said U2 will take the stage right at start time.

No tablets, selfie sticks or professional cameras are allowed inside, only small cameras.

Small, collapsible umbrellas will be allowed in the area as severe weather could develop. And, if the weather does get dangerous, the staff and on-site security personnel are trained to shelter guests.
