At a festival in Luxembourg, Green Day singer Billie Joe Armstrong had to say "good riddance" to one particularly cheeky fan.

Liam Gallagher responded to a fan who played Oasis' "Wonderwall" on stage after being invited to perform "Good Riddance" with Green Day.

The young man enlisted for this very special honor used this once-in-a-lifetime opportunity to do an extremely bold and — we have to admit — good bit. Instead of playing “Good Riddance,” he started performing the other alternative nation classic that’s also a guitar 101 standard: Oasis’ “Wonderwall.”
