Biz Markie's signature track "Just a Friend" transcended Hip Hop and etched itself directly into all of popular culture.

If you need further proof of that, check out this footage from last night's Gun N Roses show at Metlife Stadium in New Jersey.

During the same week Biz was laid to rest, Axl Rose kicked off his signature track "November Rain" by leading the crowd in a "Just a Friend" sing-along.
