'Over here musicians can be among the worst culprits, though not all of them - some of them are the best listeners I know.
You do get the odd music session where they feel like a break, ask a singer up, then go to the bar and talk loudly with their mates'

In all fairness Jim, same musicians have probably played through hundreds of nights while the singers sat at the bar making a racket only to demand total silence as soon as one them thought of uttering a few lines of song. Not to mention the dirty looks thrown when a musician happens to pluck a string, to check tuning or the key of a singer, or audibly puts down a pint glass on the bar.

These things have to go both ways to work well.
