Actually, Stranger has only been played 8 times on this tour, and not since February 28. It was done on night 7 in Newark, 4 times in Canada (Montreal, Toronto, Calgary and Vancouver), in Osaka, and just twice during the U.S. leg (Chicago and Washington). It really is too bad that Richie stopped doing it. I'm so glad that I went to Chicago.
I've been meaning to look this up, but maybe someone knows. Did Richie regularly take lead on anything before he started doing IBTFY? I know he's been doing that song for a few tours now.
