With the shows on 19, 22 and 23 already sold out, there's just 50 tickets left for 20 and 21 August.
Intriguingly, each of the nights is specially themed - as Olde Time Music Hall, Tales From The Silver Screen, Big Bands Showtime, Symphony Of Songs and Vaudeville Extravaganza in respective date order.
Duke Special, otherwise known as Peter Wilson, is playing the five night stand after a sell-out headliner at the Ulster Hall in February.
