BBC trailer music

[Moulinsart]

Does anyone know the name of the music used in a current BBC1 trailer? It sounds as though it is played on a barrel-organ and I think it comes from a film soundtrack. Thanks.

Do you know what the trailer is advertising?

Thank you squarebear. And apologies for not including that information in the question. At the time I couldn't recall but having heard the music again this morning on Radio 4 shortly before the 8 o'clock news I have remembered what it is. It is from the soundtrack to 'Withnail and I' and appears in the film over the closing credits. Appropriately it is currently being used by the BBC on radio and TV to advertise a series on cinema.
