Oh, dearie - I can top that. I once lost my voice just at the start of a one-week music camp. Where EVERYONE sings - try being the voiceless one then! It was misery (I love to sing, used to attempt to sing myself to sleep as a kid). I had to sit there and learn the parts while not being able to speak, never mind sing. Thanksfully, it came back by Thursday, and our performances where Friday and Saturday, but man, that was awful!
