I have seen Steve twice now at the Dome and although the sound was better this time due to extra curtaining hung around the walls its still not as good as other venues, at the end of the day its a sports hall.
If Steve comes to Doncaster again which i hope he does could i suggest that he has a look at the new theatre venue that has opened in the town called The Cast, it has a variety performance spaces accommodating 70 to 620 people.
