Hi Dai
From the sounds of it i would agree with Janet,except Lee Marvin was tone deaf.
Think your self lucky you can sing,at family events after a few drinks,if I made any attempt to head for the stage to sing,it use to be a race to stop me getting to the mike,even singing in the bath is banned:-(
I think singing is an expression of happiness.
I put it down to my deafness,but I do enjoy singing even though,I am hopeless.
Keep your spirit up.Eve
