Anyone raised in the 70s will be absurdly nostalgic about a stop-motion animation starring a saggy old cloth cat.

It's hard to believe that Bagpuss turns 50 this year - and that only 13 episodes were made by creators Oliver Postgate and Peter Firmin.

The animated series about a cat who comes alive alongside the other toys in 'Emily's shop', was oft repeated on TV until the late 80s and has achieved cherished status.

A whole generation grew up with Madeleine the Rag Doll, Gabriel the banjo-strumming Toad, Professor Yaffle, and the mice on the "marvellous mechanical mouse organ".

They will also remember the signature folk tunes from the series which were performed by Sandra Kerr and John Faulkner, who also voiced Madeleine, Gabriel and several of the mice.

For one special night, the creators of Bagpuss' iconic folk soundtrack will be performing the songs at Cecil Sharp House in Primrose Hill.

The October 26th gig will spirit audiences back to the enchanted shop where lost or broken toys are mended and put back in the window alongside a pink striped cat who is 'baggy and a bit loose at the seams.'

Sandra and John are joined by award-winning folk duo Nancy Kerr and James Fagan for the event, which is aimed at children of all ages "including grown up ones".

Audiences will have the chance to join in with action songs such as Row Row Row your Boat, Silly Old Uncle Feedle, The Mending Song, The Miller's Song, The Bony King of Nowhere, Saw a Ship A Sailing, The Ear Song, and Hamish McTavish.

Expect chants of 'Bagpuss, dear Bagpuss' and cries of 'heave' on the Marvellous Mechanical Mouse Organ. Augiences are urged to come dressed as their favourite character or wear a mouse mask (provided) to feel part of the fun.

Sandra Kerr will give a presentation at 4pm on The Folk Roots of the Bagpuss Music, with Bagpuss at 50, Music Songs and Stories with Sandra Kerr, John Faulkner, Nancy Kerr and James Fagan starting at 6pm.

Tickets £12-£18 from Cecil Sharp House, Regent's Park Road, Primrose Hill.
