I get a snare drummer, a bohran player and a bones player accompanying me very loudly,

The problem last Tuesday was that the sheer volume of the percussionists - and let's be honest nearly all of it was coming from the snare - that the melody instrumentalists could not hear what they were playing. Tina was sitting next to him and had to hold her concertina up by her ear to hear herself.
To be fair to Roger on bodhran; He saw the situation and played with brushes all evening - at least, I assume he was playing. I couldn't actually hear him at my end of the table.
