GARY,
I like your voice where its at now...
but how low was it before the hernia?It went up a little since the surgery. When I was a lot younger and performed with a 50's rock band, I would do all the low parts such as the words "Mother In Law" in a song by the same name, many of the Statler Brother's low vocal segments, and Elvira's oom pappa oom pappa oom pappa moow moow is still a piece of cake.  
 
 
Cheers,
Gary
