Exactly this. It also means that he doesn't have to rehearse them much and these songs are pretty much in his veins. The show was very last minute, so these choices were the easy ones in that respect. I was hoping that he would bring out One Night Of Peace as this would have been perfect for this occasion, but that would have taken some extra rehearsal, and I don't think Richie is much of a fan of doing that. But yeah, coming out and playing a bunch of solo songs wouldn't have made any sense. If it was his own show then i expect it would be a little different.
