Extracts from Trainspotting and the poems of Robert Burns are set to be performed in a 12-hour event the day before the referendum.
The open mic celebration of Scotland’s legacy to the world will feature everything from iconic song lyrics to inspiring speeches and classic comedy.
The texts will be brought life by actors, writers, comedians and ordinary members of the public in the Assembly Hall on the Mound, with those taking part urged to chose their own favourite party piece to perform.
Blabbermouth will include a mixture of spoken word and live music from a band who will perform along with a string of guest singers.
The event has been organised by the National Theatre of Scotland (NTS) and will be the final show in their season exploring themes of national identity in the run-up to the referendum.
NTS said the event would provide “an opportunity for people to come together to celebrate Scotland’s historic contribution to the world at a pivotal moment.”
Rants by Gregor Fisher’s Rab C Nesbitt character, excerpts from novels by Muriel Spark and sketches made famous by Edinburgh-born Ronnie Corbett are likely to feature in the event which ends at midnight on September 17.
It comes as details were released of a music concert being held by supporters of independence just days before the referendum.
The event called A Night For Scotland will take place at Edinburgh’s Usher Hall featuring Franz Ferdinand, Mogwai and Frightened Rabbit, organisers said.
Eddi Reader, Elaine C Smith and McIntosh Ross - a collaboration between Lorraine McIntosh and Ricky Ross - will also be on stage at the concert on September 14.
Mogwai said: “In just a few weeks we will have the once in a lifetime opportunity to take our place on the global stage and show the world what we are made of.”
Frightened Rabbit added: “This is a once in a lifetime opportunity so I would urge everyone to get involved, register to vote before the deadline on Wednesday and come along and enjoy a brilliant night for Scotland.”
Tickets for the event go on sale on Monday and cost £15.
Promoter and Yes campaigner Tommy Sheppard said: “The Yes campaign has unleashed tremendous creative energy and now a small segment of Scotland’s artistic and creative community are getting together to prepare to move up another gear in the final days before the people of Scotland make the most important decision of their lives.”
