For the under 50s.....
Sheena was from Glesga but went out to the States in the 80s, where she developed an annoying Yankie accent VERY quickly.
Came back to to play one of the very early T in the Parks at Glasgow Green in the early 90s. Bounced on stage, said "Hello Glasgow" in the aforementioned horrible fake Yankie accent, and got the usual Glesga response.
She got bottled.
