Former Ozzy Osbourne guitarist Jack E. Lee's band Red Dragon Cartel has seen more than its share of turnover lately. So, perhaps an onstage mix-up like the one in the above video was bound to happen.

Their new vocalist can be seen singing the words to Osbourne's "Now You See It (Now You Don't)" while Red Dragon Cartel dutifully play the music from an entirely different Osbourne song, "The Ultimate Sin." First-night jitters are likely to blame, as Michael Beck was making his debut late last week in Miami.

The wonder, really, is how long he carries this off. It's almost like a weird mash-up.

As owner of Arizona's Soundvision studios, Beck has previously worked with Marilyn Manson, Soilwork and others. He replaced former Red Dragon Cartel singer Darren James Smith, who split in March. The band also boasts a new bassist; Greg Chaisson announced he was quitting too. Former Ace Frehley sideman Anthony Esposito has taken over that gig.

That's part of an uncomfortable trend for Red Dragon Cartel, who released their self-titled debut in early 2014. The original lineup included Lee, Smith, bassist Ronnie Mancuso and drummer Jonas Fairley. Mancuso was quickly replaced by Chaisson, a former bandmate of Lee's in Badlands.

Lee rose to fame with Osbourne during a stint that lasted from 1982-87. They recorded two studio records together, 1983's Bark at the Moon and 1986's The Ultimate Sin. Lee was later in Badlands, a band that also included future Kiss drummer Eric Singer.
