Thanks Scott:
I guess we both belong to the "Mutual Admiration Society" (I love your renditions as well). I did listen to you when you suggested I should sing from the Head and not the diaphragm, and right you are, it's easier to sing and the audience feels more at "ease".
Jobim's music lends itself to do wonderful things with it since his chord/melody formations are so "melodious" although sometimes "intricate" due to his unconventional writing. I really miss the man.
Thanks for the positive "review", now I can put it in my new album!
Regards,
Mario
