Sara Pascoe is directing a new musical about two nannies and would-be comedians.

Nanny has been written by Alana Ramsey and Lizzie Stables, who will perform it for Radio 4 next month.

The pair play actor-nannies Amy and Lea as they juggle demanding bosses – big and small – money worries, dwindling auditions and the creeping feeling that, as they approach 40, time might be running out for their own dreams of motherhood and of forming a comedy double act.

Matthew Floyd Jones – of Frisky and Mannish fame – composed the music and also appears as the pianist for nursery rhyme time at the toddler group where the production is set.

In those moments, the pair enter an imagined world where babies’ gurgles become roaring applause as they perform musical numbers such as The Perfect Mum and Everything You Do Fails.
