h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Went to a performance of Bach's St.John passion last night - beautifully sung/played in "authentic" style. Being too vain to take my reading glasses, I was very smug about being able to understand the German (that shows the diction was excellent). Unfortunately, the conductor was ill. He spent a large amount of time, especially during the recitative, not conducting or sitting on a bar stool for the full chorus bits. I've always suspected that a well-rehearsed choir/orchestra can get along without a conductorand this more or less proved my point.

Can a well rehearsed database get along fine without a DBA? No, apparently it cannot

Hard luck.
I don't think buses and trams get on well without conductors, but I think bus conductors are a dead species

On ancient trolley busses, when the bus had to switch between overhead wire sets, it was the job of the conductor to swap the electrical contacts...really poor choice of job name, don't you think?
