Should have taken the time to see if there were other threads to this subject. Oh well!
Bev and Jerry you have it right. A little etiquette can go a long way. I'm picking on spoon players, but would you permit a person to join in on the drums, guitar or whatever instrument if they had no clue of the chords/rhythm? LTs, not trying to alienate. I can play the spoons, comb and several other cheap instruments. But I would never join in unless I asked permission first.
