Guns N’ Roses are a little bit more than halfway through their reunion tour with their original lineup. It seems like they’re having some fun on the tour, because Axl Rose had the audacity to tickle Slash while he performed his killer solo on “Knockin On Heaven’s Door.” Though it looks more like he’s going to suck his blood like a vampire in the picture above, Rose cracked a quick joke and tickled Slash a bit, which got a quick smile from the legendary guitar superhero. Watch footage of the show below. The tickling occurs around the 3:16 mark.
