Depends on where he playes. last year I saw Ray play a festival that, apart from him, only had local chart topping very lame and commercial rubbish pop groups on the bill, and Ray was stuffed somewhere between two of those acts (a girl who does this pointer sister type soulpop whatever music). While she was singing at the right-side of the (double) stage, Ray was on the left-side of the stage preparing for his own show, but most of the time he was doing those goofy dances, singalong-mimicry with her music while making hilariously funny faces.

He really was in a good mood.
Most people had not come to see him play, so when he started, only 4-5 rows of the crowd had not left to eat or do whatever it is those people do. So at that moment he could not have played a better opening song than I'm Not Like Everybody Else.
But I agree that in a smaller venue with only his own fans 'this is where i belong' would be a great opener...
