Obviously, this is an isolated incident ( a**hole ?) because Hraners are just like everyone else - people are people and you are bound to find an a**hole in any group, even singers. A short, polite talk with him, aside and privately was your best option. Publically saying what you said was as ill-mannered as he. It embarrassed him and he responded in the a**hole manner that he demonstrated when joining in without being asked.

I have refused to lay down a Hran track with a singer/guitarist on a CD because I thought it detracted from the tune. I have declined invitations to play Hran on tunes in MY OWN KITCHEN becasue I thought it detracted from a particular tune. Not all Hranners are as stunned as this guy, BUT, publically embarrassing him was definitely impolite.

Even though he gave you the gears when you apologized, it may have been the booze talking, as you mentioned, so I suggest another "explanation" when he is sober. If he gives you any grief at that point, put your foot through his Hran and then shove his tipper up his ass. There should be enough other offended people to hold him down for you.
