Songs not to play on hospital radio

When I was around 16 I worked for a local hospital radio station for a couple of years with a good friend of mine, presenting the From me to you show, with the Beatles as our backing track. We were never given the joy of being a producer (that came later) and had to sit in a room with a old microphone carved into the middle of a round table.

It was pure cheese back then, even walking around the wards you couldn't help but feel a little like smashy and nicey.

Some of the wards were for the very elderly and were full of charm and long battles with life, health and happiness- some grumbled, some moaned and some had nothing but a cheer in their heart. 

Maternity was always a strange place, very tense in some areas and very relaxed in others as each mother went through the stages of pregnancy but each sparkly in their own way. We saw 2 women twice through our time there, both laughing that we were still there doing our thing.

I digress slightly, 
While sitting there, presenting our "request show" there were always songs that you could not play, even if they were requested, and I thought you may have a a few as well to add to this list. 
I try to comically look at this, sometimes thinking about it we were so tempted when one of the older crew used to ask specifically for some great things.

Strangely "My Way" by Frank Sinatra was allowed. We worked on the basis that the guy that ran the station only ever looked at the titles and not the meanings of a song  i think it may have been one of the most requested nationally at the time but don't quote me on that

I can remember 3 songs that were on the "blacklist"

Stairway to Heaven
The first cut is the deepest 
Every Breath you take

Feel free to add some more
