Many singers complain that when they fly from one location to another they feel like they can’t sing as well. Unfortunately, as you become in demand as a singer (or for that, matter most walks of life), it means you are going to do a lot more flying. Part of your life being the front person and getting all the attention now means you are sentenced to painful airplane flights. You will now be asking for more water then the flight attendants can handle, and subsequently running to the bathroom every ten seconds! Hope the attention is worth it!
