He was way nervous you can tell. I wouldn't even be able to play one note in the same room as Les let alone be if he was staring at my fingers.. You may think it sucked but I give him credit.
OMG poor Slash he was SO nervous. He misses many notes during the solo and finds himself with nothing to do at 4:18 and bends the note to make it sound cool. Still he was able to overcome the situation at the end, but it's impossible to ignore that a 1998 Slash got that nervous after dominating the world with GNR.
