Leppard have always played 3-4 songs live off any new album. And I'd be shocked if they didn't play 3-4 on The Stadium Tour.
Def Leppard: Let's Go, Dangerous, Man Enough
Sparkle Lounge: Nine Lives, C'Mon C'Mon, Bad Actress
Yeah: Rock On, 20th Century Boy, No Matter What, Hell Raiser
X: Now, You're So Beautiful, Long Long Way To Go, Four Letter Word
Euphoria: Demolition Man,
