In Sligo there are sometimes poetry circles in the Yeats Building, Hyde Bridge, Sligo Town.This may be a good opportunity.
There are also sometimes events in Sligo Central Library called 'The Word', but I do not know if there will be any of these events held in November as it is too far in advance at the moment.
A café called 'Ósta' in Sligo Town also sometimes has the Ósta Sessions, but again I am not sure of their dates.
There are a few open mics in different pubs in Sligo but I think these are mostly for musicians. However, there are plenty of open Traditional Music Sessions that may suit.
The trad sessions can be found at the following link: http://johnthemap.co.uk/sm-file/mobile.html
These listings are updated every week and so you would be able to get accurate information in November with that link.
In County Mayo, there is Matt Molloy’s pub in Westport, which has a musician corner. There is also the Museum of Country Life, Turlough, Castlebar, and The Gallery Wine Bar, Westport (www.thegallerywestport.com
) could be another option.
I hope this helps!
