I just enjoy the whole thing.

I love to watch musicians as well as hear them. Especially fiddlers and mandolin and 'zouk players. I live in hope of picking up tips that will improve my own feeble playing.

I like to chat with the musicians. I like to chat with other people at the gig.

I like a Guinness or several.

At a pub gig I like to watch how many of the pub's regular punters know any of the songs being performed and seeing if they sing along.

I like to watch how different performers interact with their audience.

The whole thing is fun. :-)
