Brian Wilson has added a third date at London's Palladium to his Pet Sounds 50th anniversary tour.

The 70 plus date trek begins in Auckland, Australia on March 26 and hits Japan, Europe and the U.S.

On the tour, which Wilson says will be the last live performances of the album, he and his band will play the classic Beach Boys album in its entirety.

Wilson will now play three dates at the Palladium - May 20, 21, and 22.

"It's really been a trip to sit here and think about releasing Pet Sounds 50 years ago," he said in a statement.

"I love performing this album with my band and look forward to playing it for fans all across the world."

Tickets are on sale now.
