public tunes

London Underground, I applauded you when you legalised the buskers. The fiddles, the guitars, the saxophonists can lift or shift a mood as their music reverberates through echoing tube station.

I appreciate that there is an audition procedure and I've enjoyed the fact that the buskers are of a resonable standard. That's important, since once inside the station, we often can't escape that music.

But how could it have escaped your notice that the bagpipe is an outside instrument?
