It's all about good causes here at SFist. And while we're not sure if they really qualifies as a good cause, it's certainly a funny one. Matt Stewart is planning a wedding, and what really makes a for a rockin' reception is a good band. Being the superfan that he is, he thinks that he's offering a primo opportunity for fabulous publicity to one of the most enigmatic musicians of our time -- Axl Rose. From his introductory letter to Axl:

[W]ould there be a better way for you to jumpstart the new incarnation of Guns N’ Roses than by performing at a fan’s wedding, taking a dance or two with grandma, drinking a couple glasses of champagne, and vanishing into the night? It would pretty much be the greatest PR move in the history of civilization, and would immediately endear you and the band to millions of fans. Especially me.
