Don't worry, I think we'll be able to communicate just fine.
You need to pay very close attention to the instructions Ken gives in the videos and the audio workouts. Singing like a pro takes a lot of work and practice, but you can do it if you really apply yourself and work hard. Do exactly as Ken shows you and tells you in the lessons, and practice every day, six days a week. Give it all you've got.
Good luck, and good singing to you. Your new friends welcome you.
