Don't worry about it Dave. If you don't like it don't go. It really is that simple.I love malt whisky but hate gin so I do not bother to analyze why I just don't drink gin.
Singalongs are just a social events where like minded people do what they enjoy doing together so, as I said, if you are not of that mind do something else, like write to Mudcat.
You could argue 'why to people write to Mudcat which is boring rather than listen to the much more intellectual discussions on Radio 4'
It's all to do with being a part of something.
