I saw him in concert April 10th w/ Manic Drive and Superchick. I was a John Reuben fan, but I admit I didnt know all the words to all the songs.. : [shame on me]
He was SO MUCH FUN! Came out wrapped in alluminum foil, and had everyone in the crowd jumping up and down. He did a thing where he split up the crowd, one half shouted,”DANCE DANCE DANCE DANCE” and the other half,”PARTY PARTY PARTY PARTY”. That was fun. 
Then towards the end of his set, he pulled a couple up on stage and the guy rapped to his girlfriend and then proposed to her. =)
It was lots of fun and I look forward to seeing him live again!
