It's really up to the person running the session to ensure the chat doesn't take over.

A bit of banter and humour is all part of it as is info about the songs, but if care isn't taken it can degenerate into "Gardeners' Question Time" or discussing the merits of assembling old railway locomotives.


It's when two people start rabbiting on about something ignoring everyone else in the session that it gets a bit irritating.
