I have just recently started playing in public and still having guitar lessons.
I only sing and play my own stuff(have heard all the songs I like done so well that there is no point in me trying them)
And even after all the time spent writing editing adjusting and practicing I still have problems with remembering them in front of an audience.
I never hope tp play for pay sbut would still like like eventualy to be a little more professional I guess some of us are just a little slower.
Luckily the main venue I play at has an audience of the most supportive and enthusiastic music fans you could wish for and are never ever unreceptive to new songs,poems etc.
I am just atarting to get 2 or 3 of my own things in memory and these are now the ones I feel most comfortable playing and feel I give a decent perforance with maybe in Time We could all reach the 300 song mark,but then some of us do it for the joy not the statistics
