The BBC is embroiled in a row over whether to play the Wizard Of Oz track 'Ding Dong The Witch Is Dead', which has entered the charts following the death of Baroness Thatcher.
The corporation has banned records before. Notable examples include:
:: Frankie Goes To Hollywood - Relax
The song's suggestive lyrics caused a stir when it was released in 1984 and upset Radio 1 DJ Mike Read who declared it "obscene" - none of which stopped it reaching number one and selling millions of copies.
:: Serge Gainsbourg and Jane Birkin - Je T'Aime... Moi Non Plus
The saucy French ode to free love holds a place in the history books as the first number one to be banned, with its amorous lyrics and breathy vocals proving too much for the BBC.
:: The Sex Pistols - God Save The Queen
This perfectly-timed punk classic caused all kinds of problems when it was released around the time of the Queen's Silver Jubilee.
It looked set to be number one as the nation prepared to party but was eventually held off the top spot by Rod Stewart - sparking stories that the sales figures had been massaged to prevent embarrassment.
