Victoria Wood takes you  behind the scenes of the film she wrote and directed through  the whole process, skipping only the actual writing.

But the cameras have captured  the whole complicated process - from the first day of orchestral recording to the last shout of 'cut!' on a huge dance number. Looking  at the nuts and bolts of a big musical production, revealing how the choreography, musical arrangements and design all have to work together to tell the story.

How does Michael Ball hang off a ladder while singing at the top of his voice?

Victoria also looks at the real events which inspired her story.She goes back to Manchester to find out about the original choir of the 1920s, and the children who sang on the record of Nymphs and Shepherds.Victoria unpicks the process in an attempt to understand how what started as a straightforward account of a day in the life of a children's choir in 1929 ended up as a middle-aged love story about the power of music to reconnect lonely people and give them a second chance to fall in love.
