Interesting. Festivals can be large commercial affairs or supra club events in a different town. Likewise clubs can be get up and do a mini spot before a guest artiste or they can be sing around.

Many people who go to large corporate festivals wouldn't feel comfortable in a sing around and vice versa.   Friends in our village goes to some festivals but looked at me gone out when I suggested they come to the local sing around session. Likewise, I know many people for whom hearing unaccompanied traditional songs is a matter for bowed head and ernest contemplation but view a microphone as a karaoke instrument used in the next pub down the road that they have never been in.

I reckon curiosity can lead to trying the other, but sustaining it? Sometimes a very different world.
