If Judas Priest has a sense of humor, I wish they would show it off at the live shows. Lots of bands who you would think were the most serious band in the world show their humorous side during their concerts, like Rush and Genesis. This video is the Intro of the current Rush tour. Try to imagine Judas Priest doing something like this to open the show. I think it would be great!
