The Cock and Buck Story, which is taking place on Saturday, August 10, is a Totally Locally collaboration between The Roebuck and the Cock Inn in Derby Street, Leek.
The Topsy Turvy Beer Swap means punters will be able to grab a pint of Titanic in the Cock Inn or a Joules in The Roebuck, who will be working together and serving each other's beers.
There will also be live music in both pubs, with bands playing on the hour every hour; one hour it's on at The Roebuck and the next hour it's on at the Cock Inn.
Food will also be served throughout the afternoon and evening.
Totally Locally volunteer Marc Briand said: "It's great to see two great Leek town centre pubs working together in this manner and it demonstrates perfectly the whole ethos of the Totally Locally initiative.
"From a Totally Locally point of view the Cock and Buck Story is a great idea and is what the campaign is all about, getting businesses working together who would normally be in competition with each other to make the whole town better and offer something more attractive for everyone."
Alan Ward, manager at the Cock Inn, said: "The Roebuck and the Cock have always enjoyed a cordial relationship, dating back to days when they were both owned by the same brewer.
"With the new revitalised input from the two independent local brewers, Joules and Titanic, who now own these established Leek institutions, Nick and Natalie from the Roebuck and Lynne and I from the Cock Inn are glad to get together with Totally Locally for an afternoon and evening of fun, music, food and good ales."
Nick Bradstreet, manager at The Roebuck added: "Chatting with Marc from Totally Locally I was reminiscing about the days on Derby street where the customers of the two venues would spill out onto the street and join.
"This gave us the idea of doing a co-event to try and re create that kind of atmosphere between the two pubs again.
"Having already having formed a good 'landlord' relationship between myself and Alan it has become quite easy to organise this event between ourselves, even coming up with quirky ideas of glass collections in each others' pub and exchanging beers.
"I'm really looking forward to a good day/evening of beer, music and some light hearted fun between all the staff and customers."
