Kickoffs can be scary.
You are with a group of people who are all waiting for you to start your song, and you have to kick it off to get things started. Your kickoff will determine whether everyone stays on the right tempo, and it helps everyone know what song you’re singing and how it goes.
I’m still learning to do kickoffs, and sometimes they just don’t work and I have to start a second time. When that happens, I try again and off we go into the song. The important thing is that somebody has to just go for it and get things started.
