Great song, Jim.
I remember John singing it too at various festivals over the years.

Yes, everything changes and it suits some people better than others. If that's what the bar and its regular customers want, so be it.

As I (and Trish) said, there are still singing opportunities in other Edinburgh bars and more informal music sessions too. Almost every bar I know is different from what it was 50-60 years ago for better or worse.
