Well I find my egg playing session frequently interupted by fiddle players, guitarists and singers all of whom seem to think that they know how the tempo should go. My advice to all you egg players is to hold 3 in each hand and shake them like you were ringing the bell on a firetruck, stand on the table if necessary until everyone comes 'round to your interpretation of the tempo, or they leave.... Actually that tends to happen quite a lot come to think of it.
