great muse with some really good advice, work with what you have which in my case is limited but I have now worked out how to get the best out of it and as posted later you then write for what you know you can deliver well
I did have some lessons as well from a really good coach who was a bit wacky but she not only taught me to breathe correctly but had a lot of good tips on relaxing the body before I sang which was very helpful before a live set !!
I will try and dig out some of the info if anyone is interested
singers like cohen, `bill withers, chris rea, dylan were not from the hit factory cast but they all had their own sound which whether you liked it or not was part of their make up and success
