@edgarblythe,
On Pointless the other day there was a question on banned songs on the BBC. They're not all banned for upsetting public decency like God Save The Queen by the Sex Pistols.
That reached number one during the silver jubilee. It wasbanned on the BBC but still on general sale.
Walk Like An Egyptian was banned during the Gulf War because it may have upset people at the time.
Lola by the Kinks was also banned, not because of the subject matter but because it contained the line,
"Where they drink champagne and it tastes just like Coca-Cola. "
The BBC is not allowed to advertise so Ray Davis, who was in America at the time, flew back to rerecord the line so it said cherry cola.
