When I joined the RAMC, there was a bloke who had been in as a Rock Ape, (with great affection obviously) who joined with me. As soon as he put it on we were (ever so politely) asked to turn it off.
So, after some of the proverbial had been taken out of us, I asked our TC about this "ban". I got the usual stuff, but, as far as we were concerned, bloody great song, and we / I will sing it out!
