Don't Cry for Me, Maradona
When it comes to drama, most people think of TV. Granted, radio does have a long tradition, but that's mainly on other BBC networks.
So introducing the genre to 5 live would always be tricky. It had to connect with the audience, be topical and accessible. We thought football should be the subject.
But then - who and what? Football fans often hate each other, so doing something about a particular club could alienate swathes of the audience. We needed a unity figure. We needed Sir Bobby Robson.
But why now? What would be the hook? We were in luck. It just so happened that this year is the 25th anniversary of Maradona's 'Hand of God'.
So the writer Aelish Michael and I discussed different scenarios. Could we re-enact the build up and match itself? Or would it be better to look at the impact of the incident on Sir Bobby in the days afterwards? We settled on the latter.
It was crucial Sir Bobby's family were on board. This would be a fictional take on events but it had to be authentic. And it needed those distinctive Bobbyisms in the dialogue.
We decided it would revolve around a discussion between Bobby and Elsie in the aftermath of the match, and that chat would happen somewhere in the North East. We settled on a picnic at Lady Elsie's favourite beauty spot.
The next step was perhaps the most risky. Who would play Sir Bobby? There's no shortage of great Geordie actors but who would understand his passion and recognise what he might have been feeling about England being cheated out of a place in the World Cup semi-final?
In the end we decided to ask Tim Healy and his wife Denise Welch to play Sir Bobby and Lady Elsie. They knew him and they're both passionate Newcastle United fans.
The result? Well, Tim didn't want to do an impression (Sir Bobby had a softer voice than Tim), but his empathy and understanding of the man comes through in his performance. And of course, having a husband and wife team playing a husband and wife means that there's immediate chemistry between the two main characters.
It's an affectionate and poignant piece of drama but it's not just about football. In fact, as Denise Welch has said in numerous interviews this week, it's a love story.
It reveals quite a bit about Bobby the man, his devotion to Elsie and how his upbringing and passion for the North East influenced his career.
I just hope we've managed to do the great man justice and to remind people what a true gentlemen Sir Bobby Robson really was.
Ashley Byrne is the producer of Don't Cry For Me, Maradona. It's a Made in Manchester production for BBC Radio 5 live and you can listen to it again on Sunday 26 June, at 6pm.
