After school drama, dance, singing, performing arts...???

[whosforacuppa]

My DD's v keen on doing some form of performance based club/class. A musical theatre club would probably cover it all.

Can anyone suggest/recommend any companies around north London.

much appreciated.

New London Performing Arts Centre NLPAC, is very good. They cover everything a put on end of term shows for families to see. They are based between Crouch End and Muswell Hill.

I second ifonlytherewastime's suggestion. NLPAC does good themed weeks during holidays too.

There's also Jackson's Lane although haven't been there for a while. It's nearer Highgate.

In Crouch End there are dance lessons with emphasis on performance in the Town Hall Arts Centre

Not sure how old your DD is, but also classes for age 6+ here:

I recommend Dramarama, based in Hampstead. My daughter loved it. Here's a link to the listing on Camden which has the review I left.
