A Song by Irish group The Dubliner's was banned here.
The song was called "7 Drunken Nights". It was banned because of strong alcohol references

Bit stupid if ya ask me. But it was changed and now it is played on folk programs.
Oh and pretty much all Irish rebel music is banned too. Which is bad because I like it

Another famous song ye all might know is "Fairytale Of New York" Christmas song. It was banned here because of the reference to homosexuality in it.
It too has since been overturned.
