Brad Paisley fulfilled the wish of a woman who'd recently passed away by showing up at a party in her honor.

Allison Greene was hoping to throw a big celebration and have Brad Paisley be the entertainment when she beat cancer, but the young mother died last week.

So her friends created a video about the memorial and posted it on Facebook in the hopes that Brad would see it -- and he did -- more after the jump.
Brad says, "It brought me to tears, and I thought, 'Man, if I could just be there ... and I thought, yeah. I am going to be there."
