Yeah. Remember Oasis are still together. As much as I like Noel Gallagher, I think it's an arrogant thing to say that Oasis split up because he left (not that you are saying that O.P)
Ahh but will they be able to write cracking songs like Noel, I doubt it. Liam's song writting has improved a lot over the years but even his better songs do not match up to Noel's. Gem and andy are hit and miss when it comes to song writting too.
