PLEASE REMEMBER:
My father Sydney Rhys Barker created History of the Tenor in 1989. He died in 2005. He is unable to help you!
I am happy to assist if I can but I do not know anything about opera or how accurate this History is. I especially like correcting mistakes since I have no idea about opera and my fathers strong accent has made transcriptions very hard. But with your help we shall prevail!
All comments are appreciated and you will get a response.
Thank you!
Gerald
