In 1978, the late Alan Freeman gave patients at Northwick Park Hospital in Harrow a festive treat by making a Christmas Day appearance on its hospital radio station. Former programme scheduler Ronny Munster takes up the story.
I was responsible for the programme schedules over the Christmas and New Year period, so I asked Alan if he would mind popping in.
He said he'd be delighted - and that he'd come in on Christmas Day, which was unbelievable.
Freeman was "a fun-loving guy" according to Ronny Munster
He turned up with mince pies and cakes and bottles of bubbly for the staff and did a long show for the patients.
It was great; it was a relaxed and very professional Alan Freeman doing his usual best.
There was no money involved, no ego trip - he just wanted to help out. I can't think of another DJ who would have done the same.
We kept in touch while I was at the station; I was able to call on him a couple of times and he did a few station idents and jingles for us.
I knew I could call him up any time and he'd happily chat to me and help out wherever he could.
He made lots of encouraging noises to our presenters; we had a lot of young students and he would explain the techniques he used.
It was great to have a well-known figure there who was very willing to give of his experience.
He was such a character, and to hear him on our little radio station doing his "Not 'arfs" was tremendous.
And it wasn't just a quick five minutes to show his face. He sat with us for two or three hours and happily participated in our Christmas celebrations.
It's a huge loss; he was a marvellous DJ in so many aspects.
Anyone who's done any radio, whether amateur or professional, knows it's very difficult to get that kind of charisma and fluency.
He was such a strong character with a huge personality, a fun-loving guy who loved what he was doing.
He was born for radio - a consummate professional who made it all seem so easy.
