Hello Yula, You could try the Plough up at the Library. I'm sure you could get a gig up there. Keef of this forum does open mics up there and would certainly be able to advise you better than I can. Also the Forest Hill Tavern and occasionally the EDT have live music on plus there is Hoopers too. Sue, also of this forum promotes folk nights up there. Further afield there is the Half Moon in Herne Hill or the Ivy House in Nunhead. Welcome to the forum and best of luck.
