Thanks you guys,

I wasn't actually talking about singing while having the chemo administered. Rather, I am trying to figure out how feasible it will be for me to sing at the gigs that we already have lined up. If I am too sick to go, then my band will cover, but if I feel well enough I wonder if I will be able to sing or if it might hurt my voice. I can always back off and do less singing at the gigs, but I thought it might be helpful to have some idea about this for planning purposes.
