Well I was going to say my two bids worth on this subject but I think Jean said it all for me. Remember there are singers who think they can sing even when they sing off key, in other words they are tone deaf and don't know it !
I would say if someone joins SS they must be a fairly good singer and so far most of the singers I have heard on here they can sing really well.
I sing at one of my local Karaoke pubs and after doing say "My Way" no one claps, not because I am bad, because they think you are showing off, if you sound good, then the next singer comes up a bit drunk with no voice at all and even sings off key, and when he has finished the song everyone claps him ! Now can you tell me why. People are so funny in a pub but in a hall or show you would get a better reception
.
Anyway it all boils down to what God gave you when you was born, if you were lucky to be born with a good pair of tubes and learn how to use them, then you are already there, but if you didn't then its the middle of the road for most and for the others, its way down the road !
I just wrote this off the top of my head but I feel most singers on SS are real troopers !
Cheers, Peter
