Doesn't seem to have affected him too much so far - he commanded the stage on Saturday like the rock n roll general we all know and love. He's seems in pain at times, but he's battling through it. Also helps that Richie is like a man possessed on this tour and is obviously keen show to people his recent 'slip' hasn't affected him - he's on absolute fire and playing better than I've seen in years, with great stage presence too.
