Countless people have done it, and no matter how many fans say "what the hell? You've fucked that up! We just want to watch the concert", they keep doing it.
The Black Crowes - Freak 'n' Roll Into The Fog
Black Sabbath - The Last Supper
Ozzy - Live & Loud
Deep Purple - Come Hell Or High Water
Sebastian Bach - Forever Wild
Guns N' Roses - Use Your Illusion World Tour

The list is unfortunately very long. And people are still doing it. Morons.
At least Heaven And Hell, Queensryche, Solitude Aeturnus and Onslaught have all got it right recently!
