I have had a few people sing my stuff while I have been there,I Know one or two have said they felt a bit "funny" about it .
My own feelings are embarrassment for getting a credit for the song and
gratitude that someone thinks the song worth singing.
Like you Jerry I have had someone change the words to something a little less strident than the way I feel,but we are all different and it was still a boost to me ego.
I think I would would feel accepted as a writer if I went to a place I never visited before,with no one who I knew there and heard one of mine sung.
It was great to sing one at a club and have the audience join in from the off in a very definite way as if it was an old and well known song.
Purely because Ian Swinburne had taken it on in his set and sung it around the area.
I Dont suppose I will ever make a penny at it but I have a wealth of friends and good memories and that is worth more to me.
