There have been sanitised versions of songs for the benefit of the Beeb for years:

Sixteen Tons (lyrics changed from 'St Peter' to 'Say Brother' -blasphemy?)

Answer me (lyrics changed from 'Answer me Lord Above' to 'Answer me oh my love' - also blasphemy?)

Beautiful South ('Don't marry her f*ck me' to 'Don't marry her have me' obscene?)

Seem to remember the Animals House of the Rising Sun being a huge hit in part because the Beeb thought it was too long, so only played half of it - if you wanted the full version you needed to buy the record or listen to Radio Luxembourg 208 metres on the medium waveband.
