Gawd, If talent was a requirement, I'd never be able to sing anywhere.

Once someone said to me (at a songwriters circle) 'You don't have a very good voice and you don't play the guitar very well....


....But you're the best one here'.

I think it comes down to

If you want to sing
and if you have a good repertoire
and if you sing like yourself (not some Dylan soundalike)

Then go ahead and bloody well sing, 'cos no one else can do it for you.
