BOSTON (CBS) – Crowds hoping to get into the Oval for Sunday July 3rd’s Pops Spectacular Rehearsal Show, will have to wait a little longer.

Organizers have pushed back the time that gates will be opened. Spectators will not be allowed into the Oval until 5:30 pm.

“Everything’s coming together but because of the sudden change in artist where Martina McBride has stepped in We have to fly her in in the morning on the third so she’s going to rehears on the afternoon of the third then we’ll open up and get ready for a great show,” said the event’s co-producer Rich McDonald.
