David Spargo apparently really wanted to meet the band "Peking Duk," so much so that he was willing to poorly edit the band's Wikipedia entry in order to convince a security guy he belonged backstage. Lucky for him, it worked.
The ill-placed and poorly formatted "Family David Spargo" was legit enough to dupe a surprisingly gullible security guard into letting David past him, where he introduced himself to the band:
"We ended up having a bunch of beers with him and he was an absolute legend. He wasn’t a creep or anything. He was like the most normal dude we’ve ever met. That’s what makes it more hilarious."
Was it worth it? Absolutely.
Would it work a second time? Probably not.
