As to BC'ers opinions, I am seeking to see if I am being overly sensitive to this, I was really annoyed when the question arose, especially as the obvious solution was that the singer should carry and store at least some of the PA.
And to make it worse the guitarist going into sulk mode because I didn't just roll over and commit to being lumbered with half a PA.
I guess, where I am at is that if the atmosphere continues I will walk, don't need the hassle especially when I have done nothing wrong.
