I do think that an Oasis reunion, should it ever happen, has been hyped to such a ridiculous level now that it could never possibly live up to it. And it would no doubt cost £300 for a ticket and be full of the piss-throwing chavvy bell ends that end up at these gigs. They do have really strong songs though that are the best to belt out, and both Noel and Liam live are good fun.
As far as Manc bands go, The Smiths and The Roses were better for me but I think a lot of the Oasis hate is purely down to how 'everywhere' they are. In some very specific demographics they're arguably actually bigger than The Beatles, so I can see why they do some people's heads in and would be a Room 101 band.
