Donny, female vocalist are extremely difficult to find, especially good ones that are willing to work as much as the demand calls for.
Additionally, my lungs are not my only health problem - just the one that will soon take my life. My back is shot to Hell, I have the early onset of Parkinson's Disease, Macular Degeneration (dry), and distal neuropathy to name a few. Fat chance of me EVER going back to work, especially at 79 years of age. Better odds of being struck by lightning on New Years Eve.
