Pre recorded keyboards!!!

I know I'm gonna stir something up with this, but I just have to get this out to you guys(and gals)! I went with Jeremey to the Charlotte show last week, and came away extremely disappointed. I have known that Jonathon has sequenced extra keyboard parts in the songs for years. Sometimes this is necessary on songs like "Who's Cryin now" because there are string parts recorded that are impossible to play while playing the piano parts. I'm fine with that as I've played keyboards my whole life and realize that it's necessary to add components to a song that compliment your performance. What I do have a problem with is when Jonathon came down center stage and played guitar on "Chain Reaction"! The keyboards were completely pre-recorded, and Jonathon played guitar!!! Why would one of the greatest keyboardists of all time(and one of my greatest idols) play guitar on a keyboard song??? He's never played guitars on that song the other 4 times I've seen them live, and it's not like Neal needed the help! I don't know if anyone else has brought this up, but this really pissed me off! Let me know your thoughts on this.
