Hello.
I will go with John Lennon - England/UK.
He somewhat overshadowed the other three parts of the band (McCartney, Harrison and Starr / Scotland, Wales and Northern Ireland). At one point he was on top of the world, but after a period of time he gradually withdrew from the limelight. He had a good comeback with Double Fantasy (Falklands) but then died. The UK isn't dead yet, although Scotland may be independent in a few years time
