I think for people like Mark, who is obviously an introvert expresses himself very awkwardly on stage, it is way better to stick to the music. Some of the stuff he says on stage is really cringe-worthy at times. Really corny. And it's a shame, because he has a great sense of humor and is fantastic at impressions. That said, Val mentioned the NHB shows, when he's surrounded by other artists who can help him carry the show, he's a different man. Mark's music, and DS, was always pretty serious stuff (there is humor and sarcasm there, sure), so a typical Mark show doesn't lend itself to lots of banter and crowdpleasing gimmicks. And none of the band members are Mark's equal. It's not a "band". The NHB shows had a looser format altogether, Mark was not the focal point, the great Brendan Croker really pulled things along. Mark could relax a lot more. Perfect format for a guy like Mark.
