Keith unleashed that the tragic death just in age of 33 is really a great shock for him and their band members Ronan, Shane and Mikey.
Dad-of-two Keith, 37, said: “As time goes on the gaps in between become easier to manage, but dates like the anniversary are obviously tough, very tough.
“But I think Steo’s passing actually helped bring us closer together, in a way.
“It was such a tragic event and such a shock but we were there for each other and still are. It almost brought us closer having been through something like that.”
He said: “We’ve plans in place for a tour and an album next year for the 20th anniversary — that’s if people want to come and see us!
“We’ve a very loyal fanbase that always come in their thousands. It’s a nice set-up. We never broke up, so we can take time out to do our own thing, and then get back together when it suits.”
