People are being invited to take part in one of four ‘flash mobs’ to raise money for the Henry Allen Legacy fund and Macintyre.
Organised by Sleek Dance, the events will have a Christmas theme and will take place over the weekend of November 30 to December 1, with one set for December 15.
Exact times and locations will be given out at one of two rehearsals, the first of which will take place on Sunday at the Mercure Hotel Abbey Hill between 12pm and 3pm.
The second will take place on November 24 at the Woughton Leisure Centre on Chaffron Way between the same times.
People are encouraged to attend at least one rehearsal and then watch the Flash Mob briefing online – the link will be given out at the practice.
Those who want to come along need to RSVP to the event on Facebook or email email@example.com and say which rehearsal event you would like to attend, and how many people you will bring along.
The money raised through collections will then be shared between the charities.
