Gary...
Glad to hear you are feeling better. Falling ill during my peak season has always been a worry for me. In 2005 I was able to find suitable replacements when I came down with Bells Palsy and the Shingles. A mild heart attack this past May occurred during a dry spell when I wasn't booked.
As you know, I sometimes perform with a girl singer...and she has come to my rescue several times when I was able to play but unable to sing. It cost me a couple of paychecks, but kept the clients happy.
Get well soon. The Dills and Joy Juice should help.
