Leenia....."Big Al wondered what an unreal singer is.
A person who is willing to damage the voice in order to make money is not a real singer.
A person who is willing to undertake a soul-destroying concert tour which may result in collapse and hospitalization is not a real singer.
A person who willingly sings out of tune or sounds sick because it fits his genre is not a real singer. "

I have pondered the above and come to the conclusion that it is unponderable.....I don't get this at all.... Possibly missing the Mudcat "in Jokes" I dunno
In answer to the original question..as a singer/ musician I need as many songs as required to meet the diverse needs of my audience which changes all the time...
