Judas Priest’s Rob Halford said he wants his band to tour with Iron Maiden.

Although the two bands were rivals during the ’80s, Halford explained that he wanted power in numbers.

“My dream had always been to have, like, ‘The Big 4 of the U.K.,’” he told Consequence of Sound, mentioning the Metallica, Slayer, Megadeth and Anthrax shows of 2010 and 2011. “I’d always dreamed of Black Sabbath and Motorhead and Priest and Maiden as ‘The Big 4’ doing something in the U.K. Sadly, two-fourths of that has gone, but the music lives forever. That’s the main thing.”

Specifically referring to Iron Maiden, Halford said he thought “both bands would look to do that. It’s all about the timing of doing such a thing.”
