The BBC regularly shows old Top of The Pops but it has the problem that as they were presented by Disc Jockey's who were later revealed to be dirty old perverts or worse then there are some shows they can't re-show.
I saw one such show recently from 1993 which was presented by Gary Davis who never went on to sexually abuse anyone so was safe to broadcast but had the song by The Shamen called 'Ebeneezer Goode' with it's chorus which repeats 'E's are Good, E's are Good'.
As the early 90s was the high water mark for taking Ecstasy (or E's), it wasn't subtle and the BBC did later ban it but incredibly the band continued to deny it was a song about ecstasy.
Another song obviously about drugs but poo pooed by the band at the time was Golden Brown by the Stranglers but although they denied it at first, they later came clean and said it was about Heroin which surprised nobody as that's what we all assumed anyway.
The Beatles said Lucy In The Sky With Diamonds was all about a picture by John's son who had drawn his friend from school called Lucy surrounded by stars and that's about as credible as Paul saying he doesn't dye his hair.
Musical Youth's 'Pass the Dutchie' was said to be about passing around a cooking pot but turned out to be about pot alright but not the cooking type and how can Puff The Magic Dragon by Peter, Paul and Mary not be about drugs, it's lyrics contain almost every drug reference possible although the band's defence is 'who would be mean enough to write a children's song with a covert drug message?'
The answer is Peter, Paul and Mary are mean enough obviously.
