Did you know Megadeth's Dave Mustaine once rocked "The Star-Spangled Banner" on his trusty King V guitar during a celebrity softball game on MTV? The video's a little grainy, but the memory of his patriotic performance remains. Watch the clip down towards the bottom of this post.

Mustaine's rendition of the U.S. national anthem opened MTV's Fourth Annual Rock N' Jock Softball Challenge when it aired back in 1994. But the performance was filmed in January 1993 during the match between the "Homeboys" (which included Bon Jovi members plus Anthrax's Scott Ian at right-center field) and Mustaine's team, the "Awayboys" (featuring none other than outfielder Bret Michaels).

The Megadeth frontman was somewhat of a frequent guest at the annual MTV sports event in the '90s. He also turned up at the Fifth Annual Rock N' Jock Softball Challenge the following January. During that match, Mustaine played on a team with actors such as David Duchovny and Saved by the Bell's Mark-Paul Gosselaar.

These days, however, the bandleader is focused on finishing Megadeth's next album in the face of his recent cancer diagnosis. According to recent reports, the group have been holed up in Franklin, Tennessee, working with engineer Chris Rakestraw on the follow-up to 2016's Dystopia for the last several months.

But when all 2019 Megadeth shows were canceled due to his health (save for the imminent Megacruise), Mustaine said of his diagnosis, "It’s clearly something to be respected and faced head on — but I’ve faced obstacles before."

Mustaine again tackled the anthem famously turned into a guitar instrumental by Jimi Hendrix when he covered the classic version for the soundtrack of a 2014 political documentary called America.
