we have this sodding stupid argument at every juncture.

i can remember someone saying there was no connection between George Formby and Blind Blakes stuff - even though the chord sequences are identical.

Oasis's music, I admit I don't know very well.

But from the tradition.
I should say it takes:-

modal approach to singing (the Manchester accent somehow seems to contain a drone string), the anthemic type choruses, the lyricism, the metrical putty approach that is there in every ballad,
its there in the accompaniments - those haunting open strings...
