Planning. Work today helping other groups

Today i really have to get busy, i've been asked to perform in another groups music video as singer even though it took me weeks to learn our song. So i'm on repeat with there song called 'Everytime i look for you' by Blink-182 which to be honest is the kind of music i stay away from so i'm not looking forward to this one. They'll be performing in the media room i just feel bad as i'm not great at learning lyrics but i am trying my best! I have also just been shot playing drums for another group which isn't so bad as i can pick up the drums a lot better than lyrics!
