I was asked this year if I wrote my own songs and said that I did but I didn't think they were very good. The reply I got was "What the hell's it got to do with you?" Brilliant! Try them out. If the audience like them, great. If they don't, improve them. Most clubs I know are very tolerant and encourage new talent. If they don't, try another one or start your own. You'll find a musical home somewhere.
