Cast's John Power has shared an insight into the Oasis reunion tour which kicks off tomorrow. The Liverpudlian and his bandmates will take to the stage at Cardiff's Principality Stadium on Friday night, in front of a sold-out crowd as they open the entire tour.

Almost 15 years to the day after fans last saw Noel and Liam Gallagher on stage, the brothers announced last August that they had put their differences aside and would be joining forces again. Now, almost 12 months after that euphoric announcement, the wait is almost over.

Tomorrow, they'll take to the stage to perform some of their biggest hits for the first time in 16 years, a concert that fans would have never expected. The band will be joined by Cast and Richard Ashcroft across the mammoth shows taking place in Cardiff, Manchester, Edinburgh, London and Dublin.

But just hours before the doors open, John, 57, has shared his excitement, given that he and his bandmates will be the first people to perform on the tour. Speaking on Virgin Radio UK, he said: "Opening for the Oasis, it's gonna be amazing. The first chord of this tour is going to be one that I hit.

"I'm just about now getting excited. I mean, the thing is, the way I live my life and look at things is, I kind of take each day as it comes and not try and look too far ahead. But there's no doubt about it now that, you know, Friday is upon us, and the first chord of this tour is going to be one I hit.

"So it's a quite, a you know, it's going to be quite a moment, I think, Cardiff, Principality Stadium." It comes as no surprise that Cast have joined the bill, with the band having opened for Liam last year on his Definitely Maybe tour, celebrating the 30th anniversary of Oasis' debut album of the same title.

Meanwhile, Noel had previously said watching the band was similar to a "religious experience." Speaking to NME last year about the tour, John said: "We're blown away by it.

"We had the nod and were just waiting for the official announcement. Now we can bask in it. It's a stamp of approval from our peers, and I appreciate that massively."

He went on to say: "It kind of reaffirms our legacy and authenticates the road and journey that we've been on as a band. And now us, Richard Ashcroft and Oasis – talk about Northern Soul! That's some line-up." But John's connection with Oasis goes back decades, having met Liam when he was just 16.

John had gone to see his former band, The Las's, playing in Manchester, when a bold Mancuian teen approached him while he was outside smoking, asking for a cigarette. He declined, saying he was having a moment. Three years later, when Oasis were launching with their debut single Supersonic, John went to see them live. "I went to see them," he told Mojo. He added: "And Liam came straight over to me and was like: 'You told me to f**k off!' It was him, he must have been about 16 back then."

But the pair went on to laugh about the situation and the groups have since become great friends.
