Not a gig but i ended up doing five nights in a row playing Lumiere in beauty and the beast when i had glandular fever because when i was meant to be in hospital the guy covering my role got pneumonia and also went into hospital so (regrettably) i got discharged and did the show. The combination of dancing and singing with a gravelly french accent and feeling like death anyway meant i could barely speak let alone sing for a week. Illness is a bitch. Hope you get better soon
