George - I like your chocolate/shit analogy. Reminds me of Chris Sherburn asking the the soundman to turn the guitar down in the monitor and then adding "can you tune it from there as well?".

There is a fine line between "leading" a tune and dominating. I have always loved accompanying other musicians - I think this also creates a frisson of excitement for musicians and listeners. I don't believe that good sessions should be behind closed doors (except those oh-so-polite round the room things).
