I can confirm this. The Pogues toured Ireland around the turn of the year 1985/1986. They played some quirky venues like a community centre in North Tipperary that I can’t remember the name of.
I saw them on that tour with in the Bridge Hotel in Waterford. Before the gig myself and a friend went into Downes pub around the corner for refreshments. Who was sitting in front of the fire guzzling only the Pogues. MacGowan was asleep with a fedora over his face. This isn’t going to be good we surmised. Anyway we went around to the Bridge and Pogues duly arrived on stage and blew the fucking place asunder. Lads were going demented. It was unreal.
