I hope you got a good night's rest (in clean sheets!) and that you'll take all the good advice you got (Kendall, yours was spot on!).
Re John's advice, I agree completely. Tom, when you're all healed and have the green light to sing away, I will gladly come give you some vocal coaching (or you could come here for dinner and friendly schmoozing as well). I've been teaching singing for 25 years and have a few pretty simple tricks up my sleeve I'd be happy to pass along.
