You are about to listen to a BBC podcast and I'd like to tell you a bit about what goes into making one.

I'm Sadata Sese, an assistant commissioner of podcasts for BBC Sounds.

I pull a lot of levers to support a diverse range of podcasts on all sorts of subjects,

relationships, identity, comedy, even one that mixes poetry, music and inner city life.

So one day I'll be helping host develop their ideas, the next fact-checking, a feature,

and the next looking at how a podcast connects with its audience.

And maybe that's you.

So if you like this podcast, check out some others on BBC Sounds.

and even before he was born,

have sent Jason on a lifelong journey, a quest for truth and justice,

but also to connect with his father.

Probably the thing that has driven me to keep pursuing this

is because I'm kind of consciously, unconsciously chasing, trying to know who he was.

And I never really will.
