Don't know what happened to the post I sent in after Leadfingers on 27th at 4.38.am. It has disappeared without trace.
So trying again... I said I enjoyed playing with a friend as a duo, as it gave us more flexibility, depth, and opportunities for harmony, both in tunes and songs. As we are both amateurs, splitting fees doesn't come into it. Several people have said we should do more together. We use existing harmony arrangements or I write them. Not sure about the "warbling around" idea!
And I did comment also on the "bad attitude" displayed by the person who used that very phrase.
