Song by British artists would be lengthy, too lengthy since my tastes includes plenty if rock’s super groups ad more.
Songs about Britain? Hmmm.
“London Calling” by the Clash
“God Save the Queen” by Sex Pistols
“Guns of Brixton” by the Clash
“Strawberry Fields Forever” by the Beatles
“Ghost Town” by The Specials
... many more
of rock’s super groups and more. (corrected)
