It makes sense for him to sing his favourite song, with a few added big songs. Why would he get up and play songs he doesn't like? would any artist do that? how can he please all the fans? it's impossible, we all like different songs, a song I would say is amazing, someone else would say they really don't like it, nothing unusual in that. Songwriters move on, I remember Roger Waters saying on the radio in the mid 80's "If someone said to me, Right, here's a million dollars, go out and perform Atom Heart Mother. I'd say, you must be f...ing joking!!"
