And I take it that it's not boring if he plays The Voyeur of Utter Destruction and Baby Universal while the people who paid to (gasp) have a good time sit on their hands?
No, because at least then he'd be doing something different. I'm not saying he should play such songs for the entire set (though that would be quite a treat for the true fans) but there's really no reason why he can't expand his selection beyond what he's releases as singles or songs that get played all the time.
In reply to:
"I heard David Bowie play Joe The Lion!"
"I haven't heard of that song before, what's it like?"
