It was an all-star jam of epic, metallic proportions on Friday night (July 12) in Dallas, as a slew of metal dudes and hard rockers took the stage alongside Megadeth. It was a vertiable "Who's Who" of hard rock, as Slash, Zakk Wylde, Jason Newsted and Vinnie Paul joined Dave Mustaine and co. at the 97.1 The Eagle Presents BFD 2013 Concert at the Gexa Energy Pavilion. It was almost too many rock legends for one stage. Almost. 

The musicians performed their star-studded cover of Thin Lizzy's 'Cold Sweat' for the frenzied audience. So no matter where you are, you can feel like you were there taking it in, thanks to the miracle of Death Division's Jerry Montano, who provided Instagram videos.

Draiman also tweeted about the experience, after the fact, sharing his enthusiasm with Slash.

Megadeth drummer Shawn Drover, who played guitar during the live version, commented on the once-in-a-lifetime gathering of metal royalty and shared how it came to be, telling Brave Words who did what.

"We had been talking about having several of this year's Gigantour alumni come up and jam with us to the Thin Lizzy classic, 'Cold Sweat', which is on our latest record, 'Super Collider,'" he said. "Add a bit of serendipity to the situation -- Slash was also on the bill in Dallas last evening, who also knew the tune and was aboard for playing as well, made this proposed jam even more killer!!! So now we have Vinnie Paul on my kit, Slash, Zakk Wylde, Jason Newsted, David Draiman, Sean De La Tour, my Megadeth bandmates and me on guitar!!!!!"

"It's been about six or so years since I did the 'switcher' trick, which is when [former guitarist] Glen [Drover] was in the band (we used to switch instruments for the end of 'Peace Sells' or 'Paranoid' at times)," recalls Drover. "Good thing for me I learned 'Cold Sweat' on guitar way back in 1983 when the song was released, so I was ready to throw down as well. Needless to say, we all had a total blast jamming together, and it sure seemed the crowd enjoyed it as well. These kind of thing's certainly don't happen everyday, but when it does, it definitely puts a smile on my face."

There are plenty of metal fans who share that sentiment.
