Each generation has their opinion on the others. Old people say young people are rude and play loud music while young people think old people are boring and dull.

But why do we have these misconceptions? That's the question being asked by Croydon Young People's Theatre (CRYPT) in this year's production of Who's Who's Anyway at the Warehouse Theatre on Friday.

"It's about the perceptions and misconceptions young people have of old people and old people have of young people," says director Sheree Vickers.

"It started out as a community theatre project I did with my own company, Savvy Theatre, at the Charles Cryer in Carshalton and we had an inter-generational cast performing with teenagers working with people in their 70s.

"Then when we came back on board at the Warehouse Theatre I said to their artistic director Ted Craig I would like to revisit this piece and put it together with the Young People's Theatre group.

"I was able to work with some of the Warehouse playwright's as well which was good.

"There's a lot of mask work, costumes, film and music, it's a very multimedia piece."

CRYPT is a theatre group for young people between 13 and 16 that meets every Saturday afternoon during term time before getting The Warehouse Theatre to themselves for a week in the summer in the lead up to their annual production, which this year they will also be taking to the Croydon Summer Festival on Saturday.

"We will be doing a 15 minute showcase of the piece," says Sheree.

"It's the first time we have done it and there will be a number of routines from the show involving the masks and music.

"The orginal cast I did it with performed it at Guilfest a few weeks ago so we know it can work.

"I used to be a street performer in Covent Garden so when it comes to outdoor festivals I am in my element but this is an opportunity for the young people in the group to experience that element."
