911 sold 10 million singles, and had 10 UK top 10 hits. Part of the line-up was Carlisle's very own Lee Brennan.
Now, almost two decades since they were last on stage they came back to Lee's home town to showcase their comeback album.
Our reporter Fiona McIlwraith caught up with Lee at their sound check, before the concert.
