Thinking about not being able to "sing for toffee" reminded me of an incident when I was at school (1950's) and getting an end of term report which showed fairly good exam marks with the exception of music where one infamous "Christian Brother" had written "Musically speaking this pupil is dead from the neck up" This piece of paper has remained amongst my treasured possesions and possibly explains my nickname, as the same person called the banjo "The instrument of the Devil"
I always saw this as an inpiration to accomplish something musically, convinced the the Devil had no right to all the good music about in those days and I went on to play with several groups in sixties Liverpool on guitar and banjo, and now spend lots of my early retirement either making banjos (mainly for myself) or playing with the band. Not so many gigs nowadays as my early retirement was brought on by mobility problems although the hands & fingers can still rattle out a tune when needed.
Anyone can sing just need a bit of encouragement
Keep Singing
