The video will start in 8 Cancel

Steve Coogan's cult comedy show I'm Alan Partridge reaches the grand old age of 20 this year - and a Manchester bar is throwing an all-day marathon to celebrate.

Gorilla will be screening both series starring the bumbling broadcaster back to back on August 20 in partnership with the Pilot Light TV Festival.

The event will also feature an exclusive video introduction from the show's co-creator Armando Iannucci, a Q&A with actor Simon Greenall - better known as Michael the Geordie - and writer Neil Gibbons.

There'll also be Alan Partridge-themed food (cup of beans and a sausage, anyone?), drinks and activities throughout the day.

Coogan's hapless broadcaster first appeared on spoof BBC Radio 4 current affairs show On The Hour, which transitioned to TV in 1993 and also spawned a spin-off show, Knowing Me, Knowing You.

BBC sitcom I'm Alan Partridge followed in 1997, winning two BAFTAs and generating some of TV's most quotable catchphrases along the way.

Tickets to the Gorilla event go on sale at 12 noon today priced at £15 from See Tickets .

Doors open at 12 noon for the event, which runs until 8.30pm. There's no official dress code but lightweight trousers, padded gilets and driving gloves, ‘sports casual’, ‘imperial leisure’ or ‘strolling pastel’ attire are strongly encouraged.
